Question 171311


{{{f(x)=-2x^3+x^2+23}}} Start with the given equation.



{{{f(2)=-2(2)^3+(2)^2+23}}} Plug in {{{x=2}}}.



{{{f(2)=-2(8)+(2)^2+23}}} Cube {{{2}}} to get {{{8}}}.



{{{f(2)=-2(8)+4+23}}} Square {{{2}}} to get {{{4}}}.



{{{f(2)=-16+4+23}}} Multiply {{{-2}}} and {{{8}}} to get {{{-16}}}.



{{{f(2)=11}}} Combine like terms.



So the answer is {{{f(2)=11}}}.
