Final answer:

After evaluating the function f(x) = x² + 5x - 7 for x = -4, the answer is -11, which does not match any of the provided answer choices.

Step-by-step explanation:

The question asks to evaluate the function f(x) = x² + 5x - 7 at the value x = -4. To find f(-4), we substitute x with -4 in the equation and get f(-4) = (-4)² + 5(-4) - 7.

Calculating f(-4):

(-4)² + 5(-4) - 7 = 16 - 20 - 7 = -4 - 7 = -11.

Therefore, the value of the function f(x) at x = -4 is -11, which is not listed in the options provided, suggesting there may have been a typo or error in the choices given.
