    To find the inverse of this function, we need to perform some steps.

    f (x) = 2x + 9

    Replace f (x) with y.

    y = 2x + 9

    Swap x and y.

    x = 2y + 9

    Solve for y.

    Subtract both sides by 9.

    x - 9 = 2y

    Divide both sides by 2.

    (x - 9) / 2 = y

    Replace y with f^-1 (x)

    f^-1 (x) = (x - 9) / 2
