What is the domain of the function f(x)=3x/x-1?

Domain f(x) = R - {1}

As it is a rational expression, the denominator cannot be zero.

Now the function holds all real values except 1 for which the denominator will become zero which is undefined.

Therefore the domain will be all real numbers except 1.
