Evaluate the function.

Find f (-1) when f (x) = x2 - 2x - 7

A.-8

B.-4

C. 6

D. 10

f (x) = x² - 2x - 7

f (-1), this means that x = - 1.

Since you need to find f (-1), substitute/plug in - 1 into "x" in the function:

f (x) = x² - 2x - 7 Plug in - 1 into "x"

f (-1) = (-1) ² - 2 (-1) - 7

f (-1) = 1 + 2 - 7

f (-1) = - 4 Your answer is B
