Question 260138


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



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



{{{f(3)=3(27)+2(3)^2-5(3)+3}}} Cube {{{3}}} to get {{{27}}}.



{{{f(3)=3(27)+2(9)-5(3)+3}}} Square {{{3}}} to get {{{9}}}.



{{{f(3)=81+2(9)-5(3)+3}}} Multiply {{{3}}} and {{{27}}} to get {{{81}}}.



{{{f(3)=81+18-5(3)+3}}} Multiply {{{2}}} and {{{9}}} to get {{{18}}}.



{{{f(3)=81+18-15+3}}} Multiply {{{-5}}} and {{{3}}} to get {{{-15}}}.



{{{f(3)=87}}} Combine like terms.
