Question

Can anyone help me with this problem, how would you do this?

Answer 1

Answer 2

Hello! :)

the vertex form of a parabola is: y = a(x - h)^2 + k

where (h , k) is the point of the vertex :)

Answer 3

try plugging in (3, 8) for (h, k)

aka
3 for "h"
and
8 for "k"

then *temporarily* plug in (4, -3) for (x, y)

aka
4 for "x"
and
-3 for "y"

Answer 4

hopefully you can solve for "a" from there
then keep "h", "k", and "a" plugged in the y = a(x - h)^2 + k

that should get you your answer :)
