Now simplify the like terms.
9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.

Answer:
f(- 2) = 13
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = - (- 2)³ + 2(- 2)² + (- 2) - 1
= - (- 8) + 2(4) - 2 - 1 = 8 + 8 - 2 - 1 = 13
The correct answer is $20!!!
