# How do you graph f(x) = |2x + 1|?

Jun 13, 2017

This is how you graph it. Hope you can understand.

#### Explanation:

The graph of that equation is a mirrored linear equation, that mirrors when the part inside the module function equals 0:

$\left(2 x + 1\right) = 0$
$2 x = - 1$
$x = - \frac{1}{2}$

That being said, its important to note that a modular function does not have a graph when $y < 0$, as we can see on the graph below:

graph{|2x+1| [-10, 10, -5, 5]}
