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
Applying log rules leaves us with the following equation:
x^2 + 8 = 6x
Change to standard form and solve using factoring.
x^2 - 6x + 8 = 0
(x - 4)(x - 2) = 0
x = 4
x = 2
Hope this helps!
