The answer is f(-2) = 30

The question requires us to substitute the value of x into the function.

if the function is:


f(x)=-2x^3+2x^2-2x+2

then f(-2) means we only need to substitute -2 for x into the equation given.


\begin{gathered} f(-2)=-2(-2)^3+2(-2)^2-2(-2)+2 \\ (-2)^3=-8_{} \\ (-2)^2=4 \\ -2(-2)=4 \\ \\ f\mleft(-2\mright)=-2\mleft(-8\mright)+2\mleft(4\mright)+4+2 \\ f(-2)=16+8+4+2 \\ f(-2)=30 \end{gathered}

Therefore,

The final answer is f(-2) = 30
