Answer:

f(8) = 108

Step-by-step explanation:

Hello!

Substitute 8 for x in the equation.

Evaluate

  • f(x) = 2x² - x - 12
  • f(8) = 2(8)² - (8) - 12
  • f(8) = 2(64) - 8 - 12
  • f(8) = 128 - 8 - 12
  • f(8) = 108

f(8) is 108.

SHURISWARRIOR
im not the best at math but i think its 108! 8^2=64 64*2=128 128-8=120 120-12=108
