For the first linear function we are going to find two points that are inside the domain of it ( ,1) in the piecewise function: x = 1 y = 3( 1) 1 = 4 ( 1, 4) x = 0 y = 3(0) 1 = 1 (0, 1) Having two points we can graph the first linear function. For the second linear function we are going to find two points that are inside the domain of it (1,) in the piecewise function: x = 1 y = (1) + 1 = 2 (1,2) x = 3 y = (3) + 1 = 4 (3,4) Having two points we can graph the second linear function.
