Question

Use the function f(x) = 15 - x to answer the question.

Evaluate. (f · f)(2)

A) 0
B) 2
C) 4
D) 13

Answer 1

B

Explanation:

To evaluate (f ￮ f)(2) substitute x = 2 into f(x) and evaluate. Then substitute this value into f(x)

f(2) = 15 - 2 = 13, then

f(13) = 15 - 13 = 2

Hence (f ￮ f)(2) = 2
