Question

Evaluate the following: f(x) = x² + 2x – 1 for f(-2)
A.-13
B.-3
C.7
D.-1

Answer 1

To evaluate the function f(x) for f(-2), substitute -2 into the equation to get 4 - 4 - 1, which equals -1. Therefore, the answer is D. -1.

Step-by-step explanation:

To evaluate the function f(x) = x² + 2x – 1 for f(-2), we substitute -2 into the function:

f(-2) = (-2)² + 2(-2) - 1

= 4 - 4 - 1

= -1

The correct answer is D. -1.
