Question

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

Answer 1

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:

`(2x+1) = 0`
`2x = -1`
`x = -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]}
