[SOLVED] value of 1/(1-1/0) at 0

1. The problem statement, all variables and given/known data
Is the function
$$f(x)=\frac{1}{1-\frac{1}{x}}$$​
defined at $$x=0?$$

2. Relevant equations

3. The attempt at a solution
Since we have division by zero in the denominator, I'm assuming that it isn't. Am I correct?

Yes, 1/0 is NOT defined. You don't have to "assume" anything!
