Answer:
Below in bold.
Step-by-step explanation:
g(x) = x^2 – 8x + 12
Convert to vertex form:
g(x) = (x - 4)^2 - 16 + 12
g(x) = (x - 4)^2 - 4.
So the vertex is at (4, -4).
y-intercept (when x = 0) is ((0-4)^2 - 4 = 16 - 4
- that is (0, 12).
Zeros:
(x - 4)^2 - 4 = 0
(x - 4)^2 = 4
x - 4 = +/- 2
x = 2 + 4 = 6 or x = -2 + 4 = 2.
= 2, 6.
