Question 1190842: 4. Given the function f(x)=8x-x^3, x>_ 0
a) Sketch the graph of f (use a solid line, label f(x)
b) Use the graph of f above and sketch the graph of f^-1 on the same axis as in part a) of this problem (use a dashed line, label the inverse). How did you find the points to sketch the inverse function?
c) Find f^-1(x)
