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

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.
