Given the graph of f(x), determine the range of f−1(x). (2 points)
Rational function with one piece increasing from the left in quadrant 2 asymptotic to the line y equals 1 and passing through the point 2 comma 2 and asymptotic to the line x equals 3 and another piece increasing from the left in quadrant 4 asymptotic to the line x equals 3 passing through the point 4 comma 0 asymptotic to the line y equals 1.
