Answer:
c
Step-by-step explanation:
The vertex form: y = a(x - h)² + k
y = ax² + bx + c then h = -b/2a and k = f(h).
y = x² - 12x + 8
a = 1; b = -12; c = 8
h = -(-12)/(2·1) = 12/2 = 6
k = f(6) = 6² - 12·6 + 8 = 36 - 72 + 8 = -28
Answer: y = (x - 6)² - 28.

0.17 times 1345
Answer:
Step-by-step explanation:
Option 3. The quadratic function has two distinct real zeros.
The number of distinct real zeros of a function is equal to the number of x-intercepts of the function. In this case the quadratic function has 2 x-intercepts at 2 different places, this signifies that the function has 2 real zeros. Since the function is quadratic it can have only 2 zeros.
The knowledge of y-intercept is extra and has nothing to do with the number of zeros of the function.
