Question

FAN AND MEDAL!!!
Find the quadratic function y=a(x-h)^2 whos graph passes through the given points.
(8,0) and (12,-14)

Answer 1

Plug in the points for x and y, then you'll be able to solve for a and h.
What do you get when you substitute (8, 0)?

Answer 2

idk

Answer 3

Plug in 8 for x and 0 for y. Then show me what you have left.

Answer 4

0=a(8-h)^2

Answer 5

right. now you can divide both sides by a to get
0 = (8 - h)²
and you can solve that for h

Answer 6

but what did you do with the a?

Answer 7

divided both sides by a.
0/a = 0

Answer 8

the (8,0) is the vertex of the parabola

Answer 9

yes

Answer 10

so just plug in the 2nd point
\[-14 = a(12 - 8)^2\]
