Question 507550
First, let's draw the graph for {{{f(x) = 2*abs(x)}}}:
{{{graph(400,400,-5,5,-5,5,2*abs(x))}}}
The domain of the function is simply all of the possible values of the independent variable, that's x.
You are instructed to focus your attention on that part of the graph that lies between x = -2 and x = 1 ({{{-2<=x<=1}}}) so when you draw the graph, you can omit the graph for x less than -2 and x greater than 1. I couldn't show this on my drawing.
