Describing a piecewise defined function determine the domain of each piece. domain of piece 1:[ ) domain of piece 2: [ ) domain of piece 3:[ ] On a coordinate plane, line 1 goes from (negative 4, 4) to (negative 1, 1), line 2 goes from (negative 1, 1) to (1, 1), and line 3 goes from (1, 1) to (5, negative 3).
