Sagot :
Answer:
A.x=6
Step-by-step explanation:
because the x is zero.
ANSWER : D.
Step-by-step explanation:
Find the zeros of the function f ( x) = x 2 – 8 x – 9.
Find x so that f ( x) = x 2 – 8 x – 9 = 0. f ( x) can be factored, so begin there.
equation
Therefore, the zeros of the function f ( x) = x 2 – 8 x – 9 are –1 and 9. This means
