Question

Answer 1

stick a minus sign in front of it

Answer 2

y=-(x+1)^2 ?

Answer 5

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

Answer 6

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

Answer 7

Yes.

Answer 8

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 ?

Answer 9

\[\sqrt{x} ... I got -\sqrt{-x}+5\]
