Welcome to today’s video on Part 2 of Parabola/quadratics. We are going to go over the 3 types of questions you must know to answer all the parabola/quadratics questions on the SAT.
Type 1: How to find a vertex
What you need to know - Two methods to find them (-b/2a & midpoint formula of roots). Because only -b/2a was covered in this video, the midpoint method is covered in the private lecture above
How to recognize - The question will talk about the maximum/minimum/lowest/highest/vertex
What to be aware of - Vertex ONLY exists for a parabola/quadratic function - meaning the highest exponent has to be [2]. If it’s a line or a cubic function, DO NOT FIND THE VERTEX. Vertex is only applicable in the parabola.
Type 2: Representing VERTEX as Constant/coefficients
What you need to know - Vertex form: y=a(x-h)^2 + K
How to recognize - Usually would have the words “represent MAXIMUM/MINIMUM as constant or coefficients” in them.
What to be aware of - Do not get confused with representing the “roots, zeros, solutions, x-intercepts” as constants & coefficients (which is type #3).
Type 3: Representing ROOTS/ZEROS/X-INTERCEPTS
What you need to know - Standard Form - Just a factored version of the original parabola equation
How to recognize - the question will have a similar phrase like “represent ROOTS/ZEROS/X-INTERCEPTS as constants or coefficients.”
What to be aware of: Do not get mixed up with representing VERTEX/MINIMUM/MAXIMUM as constant or coefficients (Type #2)

thanks man!

This really helped, I have been having problems with SAT questions on constant or coefficient. Thanks!!

[@user-qw1lo8xi1q]

You are the best explainer ever, understanding the reason behind each formula is so much better and easier when digesting

[@leylay1447]

[@JohnSAT]

Sure! Good luck prepping!

[@AhmadAlasas-iu9pc]

love u man ur a king

[@amyth8388]

another way of solving 6:41 is by adding the two roots and dividing by two to find x-coord (-6+4)/2 and you'd find h a little faster. Great videos btw they're super helpful

[@takeover2x679]

does that work with any type of vertex form question or just this one

[@sushantofficial5002]

Hlo i am confusing why option B is incorrect for that question?

[@skytide3156]

@@sushantofficial5002 the questions is asking for the minimum value of f represented as a constant or coefficient and the constant is 24 and the coefficient is 2 meaning (-2,-24) but the correct minimum value is (-1,-25)

THE JAY PARK OUTRO!!! (thank you this video helped me a lot :D)

[@gregnixon1296]

Alternate strategy: This is a calculator question. Graph all answer options to see which one overlies the equation in the question. This is not truly a math test. It is a “find the answer” test.

[@aliceumubyeyi716]

thank you so much for doing these videos. They are the greatest help for the SAT. Could you please do a video about parabola transformations pleaseeeeeeee.

[@JohnSAT]

like shifting up & down?

[@aliceumubyeyi716]

yes the shifts of up, down, left and right

[@hopecheung8328]

These r the best videos to watch when you’re in the bathroom and realize you should do something more productive than scrolling through instagram

[@apostledaspan2627]

thankyou sir for helping

[@cresenium8908]

thank you for the video! but i wanna ask, in vertex form, how did u find x=2 y=3?

[@Kiitanseditopia]

Thank you

[@Mira59771]

when the say " x-int appear as constant" directly factor the q, and when they say y-Int appear as constant, ur answer should be in the form of a(x-h)^2+k. check ex 7 (8:59) and ex 26 (6:4) Hope this helps!

[@JohnSAT]

Totally true! I left it out b/c the video would have gotten too long, but it's another hack I teach my students. Glad you pointed it out!

[@dflex3504]

Please in sat is root or solutions generally refer to real root and not imaginary root because sometimes they don't specify and they will also give equations that don't even have a b c in the quadratic equation y=ax^2+bx+c

[@cookie_416]

At 6:40 when you expanded the equation is the answer of it in the multiple choice answers or do we have multiply all of the numbers by together?

[@mayaaa8049]

I took multiple practice sats and just from watching some of your videos, my score in math went from a 500 to a 630. im gonna keep watching them so i can get it to at least a 700. thank you so much!

[@3rdDantetherapist]

how'd it go?

[@booksaver364]

hello, your videos have helped me a lot. but can you do different types of word problems questions like rate word problems maybe or percentage

[@xdgamer4998]

❤

[@plustutoring7698]

If you just know that the x value of the vertex is always in the middle of the 2 x-intercepts these questions can be solved a lot faster.

[@JohnSAT]

^ True! - It's faster, so if you want to learn more about it, this method gone over in the private lecture in the description.

Hi! Could you please do a video on probability?

Added to the list!

[@ahmadashraf1936]

i have qn about the third one u said standard so lets just factor it why dont we just put the factored answer a lil bit easier and we try it out if it do mathc it or not ?

[@jss831]

6:22 why b just got eliminated? when we put in the numbers, it turns out true. where have I made a mistake?

[@redballado7193]

where did X^2+2x-24 came from on question number 28? I'm confused.

[@CuttingGrass___]

[@lancefile9408]

For the Sat, will I ever have to know how to get an equation into vertex form, or will I just need to know how to recognize it and all that

[@JohnSAT]

You need to know how to get it to the vertex form

[@chelseadennis7588]

very helpful video, but why did you switch the sign at 3:03 it was -2 and 4 and you wrote 2 and -4. I really don't understand, could you explain?

[@trigyadhir]

When the x-2 and x+4 are equated with zero, the signs of the constants change

[@deveshmankotia296]

in example 2 u said that the minimum value of the parabola would be its vertex... but how do you know its an upward parabola?

[@JohnSAT]

Because if you expand the equation out, you get a positive x^2, which means it's an upward parabola. Whether it's up or downward is determined by the sign of the x^2 (positive = upward = minimum vertex // negative = downward = maximum vertex)

[@slavaseyranyan3971]

It’s -9a at 4:09

[@A_E.J3768]

for your first example, the 2nd method for finding the x-intercept, you made 2 positive and 4 negative why?

[@mustafawathiq6858]

When the x-2 and x+4 are equated with zero, the signs of the constants change

[@izzaabbas5520]

We will apply same formula for minimum and maximum values of vertex?

[@JohnSAT]

yes

How did you fond x=2 y=3😢😢😢😢

[@gulzahraali]

How did you know that the roots were 2 and -4 just by looking at the equation?

[@JohnSAT]

Time stamp?

[@gulzahraali]

@@JohnSAT 3:03

[@JohnSAT]

​@@gulzahraali because the numbers that make the parenthesis equal to zero represent the roots. For instance, to make the middle parenthesis equal to zero, you would need 2. And when one of the parenthesis is equal to zero, the rest of the equation will equal to zero (because they are all multiplied together) So using the same logic, x = 2 & -4 are the roots as they make the parenthesis equal to zero.

[@gulzahraali]

@@JohnSAT Got it! Thanks!

[@catlvrzz]

wait at 2:58 -- how did you know those were your roots??

nevermind ! i got it
