What is the inverse function of f(x) = 19/x^3

Step-by-step explanation:

1)  Replace f(x) with y:   y = 19/x^3

2) Interchange x and y:  x = 19/y^3

3) Solve this result for y:  xy^3 = 19, or y^3 = 19/x, or

    y = ∛[19/x]

                                                         -1

4.  Replace this y with the label    f    (x) =  ∛[19/x]

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
