Answer:
1600
Step-by-step 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 answer: 1600!
