    Section 1.9
    Questions 35 & 36

    I am given y = f(x). To find y inverse of x, I must switch the table values for x and f(x). Yes?

    For Table 35

    f^(-1) (x) = {(3, -1), (5, 0), (7, 1), (9, 2), (11, 3), (13, 4)}

    For Table 36

    f^(-1) (x) = {(10, -3), (5, -2), (0, -1), (-5, 0), (-10, 1), (-15, 2)}

    You say?

    Very good. By the way, we are almost done with Chapter 1.
