Answer:


f(g(2))=10

Explanation:

We have the two functions:
f(x)=3x-5 and
g(x)=2+(6)/(x).

We want to find
f(g(2)).

So, let's use the second function to find
g(2) first:


g(2)=2+(6)/(2)

Divide:


g(2)=2+3

Add:


g(2)=5

Therefore, our expression is the same to
f(g(2))=f(5).

Now, we can substitute 5 for f(x). This yields:


f(5)=3(5)-5

Multiply:


f(5)=15-5

Subtract:


f(5)=10

So:


f(g(2))=10

And we're done!
