That's right laurenn_marie7. Whenever you have to reflect a function in the x-axis, you stick a minus sign in front of it. So y = (x + 1)^2 becomes y = -(x + 1)^2

Thank you @genius12 !! :) would y=x^2 be y=(1/7x)^2 when it is horizontally stretched by 7?

anonymous · Answer

Yes.

anonymous · Answer

thank you!!! @genius12 last one sorry, this one asks what y= sq root of x would be after being shifted down 5 units, reflected about the x-axis and reflected about the y-axis? I don't think mine is right... I got -(sq.root of -x)+5 ?

anonymous · Answer

$$\sqrt{x} ... I got -\sqrt{-x}+5$$
