Answer:
The vertex is (2,-16)
Step-by-step explanation:
We know that the vertex is 1/2 way between the zeros
f(x) = (x - 6)(x + 2)
0 = (x-6) (x+2)
x-6 = 0 x+2 =0
The zeros are at 6 and -2
(6+-2)/2 = 4/2 = 2
The x coordinate of the vertex is at x=2
To find the y value substitute into the equation
f(x) = (2 - 6)(2 + 2)
= -4 *4
= -16
The vertex is (2,-16)
