Question 183006


{{{f(x)=2x^2-7x+3}}} Start with the given function



{{{f(-3)=2(-3)^2-7(-3)+3}}} Plug in {{{x=-3}}}.



{{{f(-3)=2(9)-7(-3)+3}}} Square {{{-3}}} to get {{{9}}}.



{{{f(-3)=18-7(-3)+3}}} Multiply {{{2}}} and {{{9}}} to get {{{18}}}.



{{{f(-3)=18+21+3}}} Multiply {{{-7}}} and {{{-3}}} to get {{{21}}}.



{{{f(-3)=42}}} Combine like terms.
