Question

PLEASE HELP ME I NEED TO PASS!!

Find the coordinates for the vertex of the graph of the function y=3x^2-12x+12.
A.
(–2, 48)
B.
(0, 2)
C.
(–2, 0)
D.
(2, 0)

Answer 1

The vertex is at the point where velocity is equal to zero.

dy/dx=6x-12

6x-12=0

6x=12

x=2

y(2)=0 so the vertex is at the point (2,0)

Answer 2

D! The answer is (2,0)!
