Problem 2CC

a What are the domain and range of the natural exponential function f(x)=ex? b What are the domain and range of the natural logarithmic function g(x)=lnx? c How are the functions f(x)=ex and g(x)=lnx related? d How are the graphs of these functions related? Sketch these graphs by hand, using the same axes. e If b is a positive number, b1, write an equation that expresses logbx in terms of lnx.
