Domain and Range Calculator

The calculator will find the domain and range of the single-variable function.

Enter a function of one variable:
Enter an interval:
Required only for trigonometric functions. For example, `[0, oo)` or `(-2, 5pi]`. If you need `oo`, type inf.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your input: find the domain and range of $$$f=\frac{1}{x - 1}$$$


$$$\left(-\infty, 1\right) \cup \left(1, \infty\right)$$$


$$$\left(-\infty, 0\right) \cup \left(0, \infty\right)$$$
