<pre>
When you use a slash " / " for a fraction bar, you must use parentheses 
before and after it to show what is the numerator and what is the denominator.

Did you mean this:
</pre>
Find g(x),the inverse function of f(x)=(3x)/(x+1).

A) g(x)=(x)/(3+x)

B) g(x)=(x)/(3-x)

C) g(x)=(3-x)/(x)

D) g(x)=(x-3)/(x)<pre>

Or did you mean this:</pre>

Find g(x),the inverse function of f(x)=(3x)/(x)+1.

A) g(x)=(x)/(3)+x

B) g(x)=(x)/(3)-x

C) g(x)=3-(x)/(x)

D) g(x)=x-(3)/(x)<pre>

Please post again using parentheses to show what goes in the 
numerator and denominator and what doesn't.
