what is the value of f (–2)? f (–2) = 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 an open circle (negative 2, negative 2) and goes to closed circle (0, 0). A curve starts at closed circle (0, 0) and curves up through (1, 1).
