Question 170854
I'll do the first two to get you started.



a)



{{{F(x)=3x-2}}} Start with the given equation.



{{{F(-4)=3(-4)-2}}} Plug in {{{x=-4}}}.



{{{F(-4)=-12-2}}} Multiply {{{3}}} and {{{-4}}} to get {{{-12}}}.



{{{F(-4)=-14}}} Combine like terms.

b)



{{{F(x)=3x-2}}} Start with the given equation.



{{{F(-1)=3(-1)-2}}} Plug in {{{x=-1}}}.



{{{F(-1)=-3-2}}} Multiply {{{3}}} and {{{-1}}} to get {{{-3}}}.



{{{F(-1)=-5}}} Combine like terms.
