👉 Learn how to determine the transformation of a function. Transformations can be horizontal or vertical, cause stretching or shrinking or be a reflection about an axis. You will see how to look at an equation or graph and determine the transformation. You will also learn how to graph a transformation by looking at an equation and using its parent graph.

10:51 if the 9 was positive and outside why did you shift 9 units down? Please help :)

If you want to work in anything related to science, technology, engineering, or math. Not everyone wants to be a plumber bud.

thank you dude so much this really helped me so much my pre calc teacher isn't really the best at teaching he talks to us as if we know as much as he does and expects us to know everything he does and I get really confused and stressed when I cant figure this stuff out so big thanks to you my dude you really helped clear some stuff up

@manitahriri9204 3 года назад

best way to think about add or subtract inside the function is to set the equation equal to zero. for example if you set x-7=0 , then x should be equal to positive 7 (x=7) then we understand it will shift 7 units to the right. vice versa, f(x+2) -> we set to zero x+2=0 -> x=-2 so we shift to the left by two units. Hope this helps!

Isn't 10:56 supposed to be up 9 not down?

Ik he must have done a mistake!

@abelhall9922 4 года назад

weren't you supposed to shift 9 units up on the 5th trasformation or am i missing something

@fujok.9733 2 года назад

Yeah. Since if was +9, it was supposed to shift 9 units up. He must’ve made a mistake.

@barrydavis331 2 года назад

Hi Around the 2:30 mark, your demonstration of expand and compress for the c value is opposite of the vertical transformation that occurs. The function is expanding vertically (away from x-axis; your hands should move closer together) or compressing vertically (moving closer to x-axis; your hands should move apart).

How would #1 on the problem you gave us to do not be reflect over the y-axis? Its -x^2 and I thought it was over the y-axis if it was inside the function? Is that negative sign not inside the function? Please answer this if you can, I know it was 6 years ago, lol.

@FloraNovax3 3 года назад

In a problem I’m working on it says to graph g(x)=3^x+3 And then it says that the transformation of that is f(x)=3x But how? Like what is the process in order to transform the function/equation?
