What are the zeros of the polynomial function f(x) = x3 + x2 − 20x?
a. 0, −5, −4
b. 0, −5, 4
c. 0, 5, −4
d. 0, 5, 4

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
