{{{f(x)=-3x^2+5x-1}}} Start with the given equation.



{{{f(-2)=-3(-2)^2+5(-2)-1}}} Plug in {{{x=-2}}}.



{{{f(-2)=-3(4)+5(-2)-1}}} Square {{{-2}}} to get {{{4}}}.



{{{f(-2)=-12+5(-2)-1}}} Multiply {{{-3}}} and {{{4}}} to get {{{-12}}}.



{{{f(-2)=-12-10-1}}} Multiply {{{5}}} and {{{-2}}} to get {{{-10}}}.



{{{f(-2)=-23}}} Combine like terms.
