Answer:
C. All real numbers except 3/4
Step-by-step explanation:
We are given


Firstly, we will find f/g

Domain:
We know that domain is all possible values of x for which any function is defined
so, we know that denominator of any function can not be zero
so, firstly we set denominator =0
and then we can solve for x

Add both sides by 3



so, this function is defined for all values of x except at

Domain will be
All real numbers except 3/4
