The piecewise function h(x) is shown on the graph. On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 3, negative 7) and goes up to an open circle at (1, 1). The second line has a closed circle at (1, negative 1) and goes down to an open circle at (2, negative 3). What is the value of x when h(x) = −3?
