Chapter 12.20, Problem 15P

To study the approximations in the table, computer plot on the same axes the given function together with its small $x$ approximation and its asymptotic approximation. Use an interval large enough to show the asymptotic approximation agreeing with the function for large x.If the small $x$ approximation is not clear, plot it alone with the function overa small interval.
