Answer: 11
Assuming 4(2) is meant to be f(2).
Step-by-step explanation:
I'm not sure what 4(2) means. I'll assume f(2) was intended in this answer.
We have a function, f(x)=3x+5, where the value of the function depends on the value of x. f(2) means x=2, so we would write:
f(2)=3x+5
f(2)=3*(2)+5
f(2)=6+5
f(2)=11
