Steps to solve:
f(x) = 3x³ – 2x² + x; x = -3
~Substitute
f(-3) = 3(-3)³ - 2(-3)² + (-3)
~Solve the exponents
f(-3) = 3(-27) - 2(9) + (-3)
~Multiply
f(-3) = -81 - 18 - 3
~Subtract
f(-3) = -102
Best of Luck!
The final score in the video game is 67.
Step-by-step explanation:
Points earned = 50 points, 87 points
Points lost = 40 points, 30 points
