Let's say we have 3 or more lines that are connected together like the picture. Is there any easy way to merge them together into 1 absolute value function?

I already did it for the example in the picture, but it took some time to calculate. I already knew the roots of the absolute values must be the x values of the angle points (0 and 10), and I solved for the other numbers using variables and entering points from the graph into the equation.

But I really feel there must be a really simpler way that I'm missing.
