Review the graph of a piecewise function. On a coordinate plane, a line starts at open circle (0, negative 1) and goes to open circle (negative 2, negative 3). It then curves up through (negative 5, 2). A curve starts at closed circle (0, 3) and curves down and approaches x = 1 into quadrant 4. Another curve starts at closed circle (2, 3) and curves down and approaches x = 1 in quadrant 4. A horizontal line goes from closed circle (2, 3) to (5, 3). Which list represents all values of x for which the function has a discontinuity? 1 0 and 1 –2 and 1 –2, 0, and 1
