1. Let f and g be the functions given by f (x) = ex and g(x) = In x.
(a) Find the area of the region enclosed by the graphs of f and g between x = 1/2 and X = 1.
(b) Find the volume of the solid generated when the region enclosed by the graphs of f and g between
and X = 1 is revolved about the line y = 4.
(c) Let h be the function given by h(x) = f(x) - g (x). Find the absolute minimum value of h(x) on the
closed interval 1/2 2 X < 1, and find the absolute maximum value of h(x) on the closed interval 1/2 x
