Final answer:
To find f(a+2), substitute a+2 into the given function and simplify.
Step-by-step explanation:
To find f(a+2), we substitute a+2 into the function f(x) = 3(x+5)+4/5. Let's replace x with a+2:
f(a+2) = 3((a+2)+5)+4/5
Simplifying this expression:
f(a+2) = 3(a+7)+4/5
So, the correct answer is Option B: 3(a + 7) +4/a +2.
