Question

What is the reciprocal function?

Answer 1

The reciprocal function is:

`f(x)=1/x`

It's graph is as following:

This is an example of asymptote.

Since `x` can take all values except `0` for `f(x)` to be defined,
Domain: `R-{0}`, i.e., all real numbers except 0.
Range: `R-{0}`, i.e., all real numbers except 0.
