Question 1189361
<br>
With the functions you show, f(x) is a constant function:<br>
f(x) = x/x+3 = 1+3 = 4<br>
Then, since f(x) is a constant function, (f ◦ g)(x)=4.<br>
ANSWER: (f ◦ g)(x)=4<br>
I suspect that is not the problem you intended to post.  If not, then try re-posting it with proper use of parentheses.<br>
