Question

What are the zeros of the function f (2) = 12 (2 + 4)?

A. (0,0) and (-4, 0)
B. (1, 0) and (-4, 0)
C. (1, 0) and (4, 0)
D. (0,0) and (4, 0)

Answer 1

A. (0,0) and (-4, 0)

Explanation:

f (2) = 12 (2 + 4)

f (x) = 12 (x + 4)

x + 4 = 0

x = -4

12 = (0,0)

The 12 is on the outside and is multiplied to x + 4 so the 12 is considered a zero.

(0, 0) and (-4,0)
