what is the zero of the function? a.x=6 b.×=1 c.×=-6 d.×=-1​

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
