# Hyperbola: y = k / x

A graph of function

Below are some examples of different types of hyperbolas.

`y = k/x`

is called a **hyperbola**. It consists of two parts called branches. The`y = k/x`

function where `k > 0`

expresses the inverse proportionality between `x`

and `y`

.
Such proportion is often found in physics and engineering.Below are some examples of different types of hyperbolas.
