# Piecewise Functions
Piecewise functions are [[Function (in Algebra)|functions]] that are defined by multiple inner functions, each governing a particular interval of the domain.
The following notation is used to describe them:
$
f(x) =
\begin{cases}
x \le 0 & 0 \\
0 < x \le 3 & 1 \\
x > 3 & x
\end{cases}
$
Or, in Desmos:
`y = {condition: value, condition: value, etc.}`
