Question 293526
{{{f(x)=x^2+5x+7}}} Start with the given function.



{{{f(4)=(4)^2+5(4)+7}}} Plug in {{{x=4}}}.



{{{f(4)=1(16)+5(4)+7}}} Square {{{4}}} to get {{{16}}}.



{{{f(4)=16+5(4)+7}}} Multiply {{{1}}} and {{{16}}} to get {{{16}}}.



{{{f(4)=16+20+7}}} Multiply {{{5}}} and {{{4}}} to get {{{20}}}.



{{{f(4)=43}}} Combine like terms.
