Graphing a quadratic with reflection and vertical stretch

[@haechansegg4178]

im cramming for my alg2 final tomorrow!! ion even remember this, but apparently i did it in the beginning of the year

[@RealBelalMuhammed]

How was it

Thank you so much!! This video was so helpful for my Algebra 2 class!!

[@TheRainbowToyChannel]

You are such a good teacher! Finally clicked for me :) thank you so much!

[@CarlPettyIII]

Thank you for posting this, it really helped me with my math homework

[@brianmclogan]

awesome! happy to help

[@ElizabethHernandez-fw3zi]

This video really helped me understand my math homework:) thx

[@brianmclogan]

Cheers Elizabeth, Keep working hard.

[@kenny9633]

thanks for posting these videos it helps alot for revewing concepts in the sat :D

[@neverending3270]

I got lost in the ending 😂

[@josuedavid6584]

dude, you are the best teacher ever.

[@brianmclogan]

thanks, just happy to be able to help!

[@HardikKundalwal]

@@brianmclogan not really, Patrick jmt and Eddie woo understand better than you.

[@evelins6563]

Omg I watched so many videos on this subject and I was getting even more confused. Finally I understand!!! You’re so easy to understand. Thank you so much 🥹 your videos are super helpful!! New subscriber 🫡

This is weird, but I love how fast you talk- it makes it easier to pay attention.

[@musclestudios6620]

How did you get two points off to the right at 3:06?

[@shaunwu3609]

Muscle Studios that’s the line of symmetry

[@OliviaSutton-h2p]

if your graph had a reflection about the y-axis, how would that be expressed in the y=a(x-h)^2+k equation? I know that a reflection about the x-axis occurs when a

[@brianmclogan]

The x would have a negative coefficient

Just a bit too fast for me

[@brianmclogan]

I understand, and I know

[@johnjohnson4610]

Brian McLogan that's okay

[@HBoywasdocile]

ever heard of a PAUSE button

[@alonzoarmendariz4057]

Great teacher!

[@Mofiac]

It isn't a horizontal compression because it isn't ( 0 < |a| < 1 ). It's a vertical expansion by a factor of 2 ( |a| > 1)

[@brianmclogan]

Correct

[@lubnanisar2407]

thankyou so much, honestly your channel is so helpful.

[@Juliaorth]

Weren’t you supposed to reflect over the x-axis major the vertex (1,-3)?

[@neonfire9036]

how do yo do it without graphing

[@collins3919]

why does the 2 go down after being squared??

[@sebastiantorres5565]

i really PRAY you see this. in class we're learning the vertex is a and k instead of h and k. PLEASE HELP

[@Аянп-н5л]

In the function, what if "a" was equal to 1. If its negetive it reflects. If its between 0 and 1 its a vertical stretch. If its over 1 its a vertical compression. But what if it equaled one.

[@brianmclogan]

then there is no effect on the graph

Brian McLogan how to solve 2-1/2(x-5)^2 By graphing

[@nikespikey3635]

Good question bro

[@Astro-tw5lj]

Love bro 🙏🙏 keeping me from failing

You're the best. SIR Love & Huge Respect from Pakistan

cheers Saad!

that was just what i needed

[@jessicanigliazzo7863]

THANK YOU SO MUCH!!!!!!!!!!!!

[@brianmclogan]

you are very welcome!

[@josuecanales1625]

Good teacher

[@souperman6406]

how do you graph when you have a reflection over y axis? like (-x-1)^2+3

[@kfjfkeofitorhf9520]

2X^2++4++3 2X^2++7

[@souperman6406]

@@kfjfkeofitorhf9520 thank you, but I'm in calculus 3 now, lol

[@bokcalinga9112]

i think u should show how'd you get that stuff from here to here.

[@collins3919]

this is somewhat confusing to me still

[@parisht2381]

I know and it seems so simple

[@fatwebb8008]

I hate being slow at math

[@brianmclogan]

I am really slow at writing a good paper, it takes time, don't be hard on yourself,

[@ikrammathematics5568]

What about this (x^2 )+(y-((x^2)^(1/3)))^2 = 1 please !!

[@alexmonroe593]

wish you were my teacher

Why he's class too quiet

WHY THE FUCK IS THIS HALF WAY THROUGH A GCSE MATHS PAPER...

[@theghostofkinglear]

What

[@selahhamad1644]

I think You're wrong. We have vertical stretch not a horizontal compression.

[@brianmclogan]

Yes a vertical stretch!

[@balajamjad8484]

It’s very fast :(

sorry about that

Your so confusing
