Homework Help: Solve for x in terms of y

  1. Dec 5, 2008 #1
    1. The problem statement, all variables and given/known data


    The function f is defined by y=f(x) = 3ln4x 0.01<=x<=1

    a)Solve for x in terms of y and hence find the formula for the inverse function f^-1(x)

    b)Write down the domain of f^-1

    c)Plot f from x =0.01 to x=1 and than plot f^-1 on the same axes but only for domain values of x given by the range of f

    d)Describe the geometric relationship that you can see between f and f^-1

    plse assist as iam very confused with functions.....!!

    2. Relevant equations

    ??

    3. The attempt at a solution

    Re: functions

    Then start by reviewing the definitions and basic rules. What is the inverse function to ln(x)?
