Evaluate the Function for the Given Input

Find f(-2) for the function  f(x) = -3x³ - x² + 2x - 8

---

f(x) = -3x³ - x² + 2x - 8
f(-2) = -3(-2)³ - (-2)² + 2(-2) - 8   {substituted -2 for x}
=  -3(-8) - 4 - 4 - 8   {evaluated exponents and multiplied}
=  24 - 4 - 4 - 8   {multiplied -3 by 4}
=  8   {subtracted}
