For the function f (x) = (-6x - 2)^2 , what is f (-7)? a. -40 b. 40 c. 80 d. 1600 e. 1936

1600

Explanation:

If the equation starts with f(-7), then we have to replace the x in the equation to -7.

f(-7) = (-6 (-7) - 2)^2

Next, we multiply -6 and -7 to get a positive 42, since a negative number multiplied by a negative number is a positive number. Then, we subtract 2 from 42 to get 40. Finally, we square 40 by 2 (40 * 40) to get our 1600!
