What is the name of this function?

1 / x

Inverse..... it's known as taking the inverse of a number.... the inverse of 2 is .5 (1/2) .... the inverse of 4 is .25 (1/4) .... the inverse of 3/8 is 8/3 (or 2.66666666) And to be truer, that doesn't actually have a function name, but it's part of the Inverse Function class of operations.

More on inverse functions (yes, there's more than one kind....) and if you scroll down far enough.... further.... keep going, there's a chart where you will find the formula you just posted.

Otherwise known as a Reciprocal

Or

x^-1

I think he wanted hyperpobla

Reciprocal, which yields the multiplicative inverse.
