On a coordinate plane, a piecewise function is comprised of a line and curve. The line starts at open circle (negative 2, 0) and goes toward (negative 4, 4). A curve starts at closed circle (negative 2, negative 8) and goes through open circle at (0, 0). The curve continues through (4, 2). On a coordinate plane, a piecewise function is comprised of 2 lines and a curve. A line starts at a closed circle at (negative 2, 0) and goes through (negative 4, 2). A curve starts at an open circle at (negative 2, negative 4) and curves to an open circle at (0, 0). From the open circle at (0, 0), a line goes through (4, 4). On a coordinate plane, a piecewise function is comprised of 2 curves and a line. A curve starts at closed circle (negative 2, 0) and curves up through (negative 3, 1). A line starts at open circle (negative 2, negative 2) and goes to closed circle (0, 0). A curve starts at closed circle (0, 0) and increases through (1, 1).
