The equations i used for this graph were: y-2x+2, y=sqrt4-2x, and y=x-2^2. To get rid of the part of the graph i didn't want to show, i had to put in "{}" x< or equal to 0, 0 < or equal to 0 < or equal to 2, and x > or equal to 2. Putting those along with their equation made the part of the graph i didnt want to show disappear. Creating a piecewise function.
