***Idk im kinda confused... please explain?? thanks :)

Answer 1

i feel like it is either shifts up or to the right... is that a right guess?? if so, idk which one it is tho :/

Answer 2

If the parent function is

f(x) = x^2

then the new function

f(x) = a(x-h)^2 + k

allows us to translate (ie shift it around) and stretch/compress it

Answer 3

The value of k is what does the shifting up/down

Answer 4

So k = 7 does what?

Answer 5

shifts to the right 7 units??
