(a) If a graph is symmetric with respect to the x-axis and the point (-2, 3) is on the graph, then what point is also on the graph?

(b) If a graph is symmetric with respect to the y-axis and the point (-1, 3) is on the graph, then what point is also on the graph?

(c) If a graph is symmetric with respect to the origin and the point (-1, 3) is on the graph, then what point is also on the graph?
