Answer 1

hey :)

Answer 2

hi :)

Answer 3

do you know how to do this problem?

Answer 4

Isn't there a standard formula?

Answer 5

(x - h)^2 = 4p(y - k)

Answer 6

i tried doing it but i got y=1/32 * (x-4)^2 - 3

Answer 7

some weird answer

Answer 8

Now just multiply it out.

Answer 9

did you get that too?

Answer 10

what do h, k and p stand for?

Answer 11

h and k is the vertex

Answer 12

p= k-y so p =8
