The graph of f^-1 (x) is called the inverse function of f (x). The relationship between the two is that the point (x,y) is on the graph of f (x) if and only if the point (y,x) is on the graph of f^-1 (x). This means that if the point (2, 7) is on f (x), therefore the point (7, 2) is on f^-1 (x). Answer: (7, 2)
