I need help from c to e, (the function is at the bottom of the image)

a. Show that f 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. d. Calculate (f -1) (a) from the formula in part (c) and check that it agrees with the result of part ( b ). e. Sketch the graphs of f and f-1 on the same axes. Answer 38. f(z) = Vx -2, a = 2
