5. Suppose there exits positive differentiable a(x) and B(x) such that
a (x) – B° (x) = 3, and
a'(x) = 58(x)
(a) Assuming that a-1(x) exists (i.e., the inverse function of a(x) exists), compute an explicit
formula for [a(x)]'. Hint: Follow the five step process we used to compute the derivative
of In(x), arctan(x), etc.
(b) (Harder) Assuming that B-'(x) exists (i.e., the inverse function of 3(x) exists), compute
an explicit formula for [3-1(x)]'. Hint: Same basic idea as part (a), but you may need to
differentiate the first property to generate a way to convert B's into as.
