Graphing and describing transformations of a quadratic equation

[@alyssafuchs9449]

i am a junior in high school and i have never had a decent math teacher in all my years of schooling. i am currently taking pre calc and i have struggled since the beginning of the year. but now thanks to your videos, i actually feel confident walking in to take the test tomorrow. thank you so much!!!

[@aidensautter4581]

I'm kinda in the same boat, I just started taking college classes in my junior year and it has been getting really stressful. This video is me where I struggled most in the class so far, so thank you Brian for being a good teacher for all of us, and thank you Alyssa, I feel less alone. : )

Math requires knowledge of fundamentals to advance. Good on anyone who is spending extracurricular time to reinforce concepts. By that same token, you should not be too worried when you struggle with a new concept. It only means you need to practice it and its precursors!

[@eleseyz7412]

That's why I like making short videos for you

[@xeeshahzad1730]

I have taken Math's 3 times and this is the only time I am actually understanding something and that is because you teach thoroughly. Amazing and simple tactics.

[@stevensmith9935]

@Kimberly Land since its in the parentheses with the x we know it's a horizontal translation, but the math is weird with it, if it's negative it translates right, if it's positive it will go left.

[@glassesuser585]

@Kimberly Land I believe because it’s positive, it goes right when it’s negative

Some teachers just assume that students automatically know these things so they don't explain in depth. But there's students like me who always needs a refresher before you start ne up in the new unit or else I just get really confused on where things come from.

I wish you were my teacher back in the day. I have a question regarding the transformations, I understand how to shift x and y wiht in my graph, however, I don't quite understand based on the quadratic linear equation f(x)= a(x+b)^2+c , how do i find a?

[@n11124]

Substitute f(x) with a y coordinate point, and all the x values with the same point of where the y value is. So if I were to find a, I'd have to find a specific point on graph, and find those two x and y values and just Substitute them

But what if the number outside the parenthesis is a number greater than 1 or -1 like 2 and -2? Is that what stretch and shrink is all about? I am a little confused.

At 4:19 how do you get 4 as your y coordinate?

[@itz_corbis1784]

The x is negative 1 so -1x+5 equal 4

Hey what aboit he vertical and horizontal translation?

[@stephalabat]

this helped alot.

[@aadilmiller3899]

I really appreciate your teaching sir it helped me a lot. but i just have a little confusion about graph's reflections..? if its multiplied by -1 out side of parenthesis. it reflects the graph vertically and horizontally if its multiplied inside of parenthesis. but -f(x)= -y and f(-x) is still equal to -y sir aren't they both reflecting vertically...? thanks for the video though.it was helpful.

[@brianmclogan]

everything you stated is correct and your last point the function you describe f(x)=x the vertical and horizontal reflections are the same. This is also true for any odd function such as f(x)=1/x or f(x)=sin(x)

[@simsvmusic]

Thanks for the help.. Didn't understand the 2 or -2 horizontally compressing the graph.. Why not vertically..

[@brianmclogan]

there was not compression in this video, confused to what you are referring to

[@brookgiles2709]

god bless this man

[@laramoss777]

How would you describe y= x+ 7. Is the graph of y= x where the slope is increased by 7? Or is the graph of y=c translated 7 units up?

Is there a difference between transformation and reflection, ooorrrrr-???

[@joypatel9444]

Now if you want to know the more points on graph after that , what should we do to know the other points?

[@brianmclogan]

plug in values for x to find the values of y that correspond

[@codygruberg7294]

FX= (-2X+5) when plotting my parent graph of anything and dealing with X, do I shift left then compress? or compress then shift left?

[@beccasouthwick]

Cody Gruberg I’m sure you’ve already figured this out but when you’re transforming in the x direction , translate and then stretch

[@michelmontoya9326]

I'm still a little confused about it being squared. What does that do?

[@brianmclogan]

look at the graph and table on desmos y=x^2 to see what it does

[@brianmclogan]

it will not matter

[@dariawinzoski8152]

sorry, i still don’t get how it shifts to the left

When you add inside the parentheses, it’s goes to the left. When you subtract, it goes to the right
