a)compare the rates of growth of f(x)=x^0.1 and g(x)=ln(x) bygraphing both f and g in several viewing rectangles. When does thegraph of f finally surpass the graph of g?

b) graph the function h(x)= (ln(x))/x^0.1 in a viewing rectanglethat displays the behavior of the function as x-->infinity (xapproaches infinity)

c) find a number N such that
x>N then lnx/x^0.1<0.1
