Lets evaluate

Start with the given polynomial

Plug in

Raise -2 to the third power to get -8

Raise -2 to the second power to get 4

Multiply 2 by 4 to get 8

Negate any negatives

Now combine like terms

So when ,

Lets evaluate

Start with the given polynomial

Plug in

Raise 0 to the third power to get 0

Raise 0 to the second power to get 0

Multiply 2 by 0 to get 0

Remove any zero terms

So when ,

Lets evaluate

f(x)=-x^3-2x^2-x-3
f(-2)=-(-2)^3-2(-2^2)-(-2)-3
f(-2)=-(-8)-2(4)+2-3
f(-2)=8-8+2-3
f(-2)=-1
-----------------------------
just replace x with 0 then 2 & solve the same way.
