Question: 410

14. If f(x) = x2 + 2, which of the following could be a value of f(x) ?

A. -2
B. -1
C. 0
D. 1
E. 2

Correct Answer: E

Explanation:

E Because any value squared must be 0 or positive, the least possible value for x2 is 0. This means the least possible value of x2 + 2 is 2. So, A, B, C, and D are not possible values for f(x). Only E is a possible value because when x = 0, f(x) = 2.
