Pumpkin ProjectYou are going to make a design for a jack-o-lantern using piecewise functions. You must not only sketch the line on the graph, but also write the function for the line with the proper restricted domain/range. In the table below, record your function and its domain and range as you create your sketch. Required # of Functions: 10 (at least 2 must be absolute value functions.)
