what is the domain of $f(x)=\frac{3x}{x - 1}$?\no all real numbers\no all nonzero numbers\no all real numbers except 1\no all real numbers except 3
Answer
Explanation:
Step1: Recall domain - definition
The domain of a rational function is all real numbers except where the denominator is zero.
Step2: Set denominator equal to zero
