SAT Math Multiple Choice Practice Question 410: Answer and Explanation
14. If f(x) = x2 + 2, which of the following could be a value of f(x) ?
Correct Answer: E
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.
