For questions 35 and 37 onlya) Show that  is one-to-one.b) Use Theorem 7 to find (f^-1)’ (a) .c) Calculate f^-1(x)  and state the domain and range of f^-1 .Calculate (f^-1)'(a) from the formula in part (c) and check that it agrees with the result of part (b).Sketch the graphs of f and f^-1  on the same axes.
