## anonymous 4 years ago How to create a nice piecewise function?

1. anonymous

$f(x) = |x+4| = \left\{\begin{array}{rcc} x + 4 & \text{if} & x \geq -4 \\ - x - 4& \text{if} & x < -4 \end{array} \right.$

\begin{array}{rcc} what does rcc means?

r stands for row, c stand for colum. So you have 1 row and 2 columns
