Consider the function f(x) = Vx - 6. (A) Find f (6) = 42 (B) Use Theorem 7, page 156 of the Stewart Essential Calculus textbook to find (f-1)' (6) (f-1)'(6) : 12 (C) Calculate f () and state domain and range of f-1. Use interval notation. If needed enter inf for co or -inf for -Do. f-1(ac) = x- + 6 Domain = (-00,00) Range = [6,00) Calculate (f-1)'(6) from the formula for f (a) and check that it agrees with the result of part (B)
