To get this function I looked at all the past graphs that I had already found the equations for and put them all in one equation. But the fourth graph only showed pieces of each graph so I knew I had to limit the domain for each piece. So I used the format of a piecewise function and I limited it when it looked like the graph changed. I figured that since the graph was y=-3x+2 until x was 0 then I would put it as "if x < 0". I used this reasoning to figure out each piece of the function. The domain is the first coordinate from the first piece of the function and the last coordinate is the same as the last coordinate of the domain of the third piece of the function. I found the range by simply looking at the graph. It ended up being the same as graph 3 and the first coordinate was the same as graph 2, while the last coordinate was the same as graph 1.
