Question

How do you graph `y = abs(x - 3)`?

Answer 1

graph{|x-3| [-10, 10, -5, 5]}

Explanation:

First, imagine the function without the absolute value (`y=x-3`).
Than, the function would look like this:
graph{y=x-3 [-10, 10, -5, 5]}

With the absolute value, all negative values turn positive. Therefore the graph looks like this:

graph{(|x-3|-y)=0 [-10, 10, -5, 5]}
