Question 1070862: How would I go about graphing this?
│x+1│+│2x-1│= y
I've got the cusps (-1,0) and (1/2,0) plotted but I don't know where to go from there. Please explain what to do.
Thank you

Look into the lessons
    How to plot functions containing Linear Terms under the Absolute Value sign. Lesson 1

in this site.

The plotting strategy is to break up the entire set of real numbers into sub-domains (ranges) where the absolute value
of a linear term is a linear function,
and then to combine and to plot all these piecewise linear functions.

In order to break up the entire set of real numbers into sub-domains (ranges), where the absolute value of linear terms
is a linear function, you should analyze the functions that are under the Absolute Value sign.
