Which statement correctly identifies a point on the graph of f–1(x)? The point (4, –7) is on the graph of f(x), so the point (7, –4) will be on the graph of f–1(x). The point (–2, 15) is on the graph of f(x), so the point (2, –15) will be on the graph of f–1(x). The point (–4, 19) is on the graph of f(x), so the point (–4, –19) will be on the graph of f–1(x). The point (10, –14) is on the graph of f(x), so the point (–14, 10) will be on the graph of f–1(x).
