Answer 3

This should be in your notes. All you need is the definition of a reflection over the y axis.

Answer 4

@Jadeishere do u know it? i dont get it i already looked up the definition

Answer 6

Well, to reflect something over the y-axis, what should happen to the x?

Answer 7

So, to flip over the y-axis, what should you do?

Answer 8

mmm switch them?

Answer 9

multiply? i dont know

Answer 10

Yes, switch them.

f(x) = a (x-h)^g + k
when you switch the x, it will do a reflective translation...

Do you understand, or would you like more assistance?
