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
So first you do the parenthasees so 2+3=5
[5]4=20
I'm nnot sure what the _ is but I'm guessing that is is minus
and the : might mean divide so
20-15=5
{5}45/45=5
