Answer:
your answer will be f(2)=10
Step-by-step explanation:
first what you want to do is substitute x=2, how do you know that? because of f(x) and f(2), like this
f(x)=3(x+4)
f(2)=3(2+4)
then you distribute 3 which will give you
f(2)= 6+4
and then you just add the rest
f(2)= 10
and that's how you get it, hope if helpful :)
