Question

What are the zeros of the function? Graph the function.



A.

–3, 3, –4

B.

–3, 3, 4

C.

3, –3, –4

D.

3, –3, -4

Answer 1

where is the function ?

Answer 2

y=(x+3)(x-3)(x-4)

Answer 3

set y=0 to find the zeroes :

0 = (x+3)(x-3)(x-4)

Answer 4

at least one of those factors must equal 0 for the entire product to be 0 :

0 = x+3
or
0 = x-3
or
0 = x-4
