Question 353722
You should get a number (not an algebraic expression) as an answer



First, calculate the inner function f(2)



So {{{f(2)=2+2=4}}} (plug in x=2 into f(x)), which gives us {{{f(2)=4}}}



So this means that {{{g(f(2))=g(4)}}} since {{{f(2)=4}}}



So from here, plug x=4 into g(x) to get {{{g(4)=-3(4)=-12}}}



So {{{g(4)=-12}}}



and equivalently {{{g(f(2))=-12}}}
