Reflect f(x)=x^2 about the y-axis. What changes?

Question

Can someone help

Answer 1

It will be the same graph. y=x^2 is same as y=(-x)^2

Answer 2

Since any positive number squared is equal to its negative opposite squared, there will be no change to the graph if reflected across the y axis.

 

2^2=-2^2, 3^2=-3^2, and so on. ..

Answer 3

Nothing, Jose, nothing changes. y = x²  is symmetric with respect to the y-axis.

Plug in numbers and try it out. The negative of all your numbers should give you the same result as the positive ones.
