Which graph shows rotational symmetry? On a coordinate plane, a sine curve goes through one cycle and is represented by f (x). The curve has a minimum of (2, negative 2), a maximum of (negative 2, 2), and goes through (0, 0). On a coordinate plane, the function g(x) has two connected curves. The first curve goes through point (negative 3, negative 2) to (0, 0). The second curve goes from (0, 0) through (2, 3). On a coordinate plane, the function h (x) is a v shape that opens down. The function has a vertex at (0,0) and goes through (negative 4, negative 4) and (4, negative 4). On a coordinate plane, a parabola opens up. It goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4).
