A piecewise function g(x) is represented by the graph.

On a coordinate plane, a piecewise function has 3 lines. The first line has an open circle at (negative 2, negative 2) and it continues horizontally to (negative 5, negative 2). The second line has a closed circle at (negative 2, 0) and then continues up to an open circle at (1, 1.5). The third line has a closed circle at (1, 4) and continues down to (5, negative 4).
Which functions represent a piece of the function? Select three options.
