Question

(30 POINTS) Which graph best represents the function f(x) = (x − 1)(x + 3)(x − 3)?

Answer 1

Answer:

C

Step-by-step explanation:

f(x) = (x − 1)(x + 3)(x − 3)

This functions has 3 zeros as 1 ,-3, and 3

Lets evaluate the function at 0

f(0)  = (0 − 1)(0 + 3)(0 − 3) = -1 * 3 * -3 = 9

f(2)  = (2 − 1)(2 + 3)(2 − 3) = 1 * 5 * -1 = -5
