Question

How do I find the range of the function `y=1/x`?

Answer 1

The range of a function is the set of all possible function values. This particular function `y=1/x` is a reciprocal function, and the only real number which cannot be written as the reciprocal of a real number is 0; therefore, the range of the function is all real numbers except for `0`.
