The question is about inverse not reciprocal!
The inverse of the function y=3x+5/4 is:
y=3x+5/4
3x=y-5/4
x= y/3-5/12, or
y=x/3-5/12.  This is the inverse of the function: y=3x+5/4

An expression is given, not a function. Therefore the inverse of a function is not requested. Inverse, as related to fractions, has the same meaning as reciprocal.
