Question #N287
The function *f* is defined by *f*(x) = 2x<sup>2</sup> + 3x - 1. What is the value of *f*(-2)?
A. -9
B. -3
C. 3
D. 9
Correct Answer is: A
Substituting -2 for *x* in the function *f*(x) = 2x<sup>2</sup> + 3x - 1, we get *f*(-2) = 2(-2)<sup>2</sup> + 3(-2) - 1 = 8 - 6 - 1 = 1. Therefore, the value of *f*(-2) is -9.
