What is the domain of #g(x) = 3 / (9 - 4x)#?
Refer to explanation
We need to find the values that nullify the denominator and exclude them
hence we have that
So the domain is
Have a look.
The domain is the set of
In this case the only value NOT allowed is the one that makes the denominator equal to zero, which is
The domain will then be all the real
