# 1


{{{f(x)=3x^2 - 2x + 5}}} Start with the given equation.



{{{f(1)=3(1)^2 - 2(1) + 5}}} Plug in {{{x=1}}}.



{{{f(1)=3(1)-2(1)+5}}} Square {{{1}}} to get {{{1}}}.



{{{f(1)=3-2(1)+5}}} Multiply {{{3}}} and {{{1}}} to get {{{3}}}.



{{{f(1)=3-2+5}}} Multiply {{{-2}}} and {{{1}}} to get {{{-2}}}.



{{{f(1)=6}}} Combine like terms.



-----------------------------------------


# 2


{{{f(x)=3x^2 - 2x + 5}}} Start with the given equation.



{{{f(-2)=3(-2)^2 - 2(-2) + 5}}} Plug in {{{x=-2}}}.



{{{f(-2)=3(4)-2(-2)+5}}} Square {{{-2}}} to get {{{4}}}.



{{{f(-2)=12-2(-2)+5}}} Multiply {{{3}}} and {{{4}}} to get {{{12}}}.



{{{f(-2)=12+4+5}}} Multiply {{{-2}}} and {{{-2}}} to get {{{4}}}.



{{{f(-2)=21}}} Combine like terms.


-----------------------------------------


# 3



{{{f(x)=3x^2 - 2x + 5}}} Start with the given equation.



{{{f(a)=3a^2 - 2a + 5}}} Plug in {{{x=a}}}. Since there are no common terms, we cannot simplify further.
