Consider the function f(x) = 8/x-7 for x > 7. Find f -1(8) = 8 Use Theorem 7. page 153 of the Stewart Essential Calculus textbook to find (f-1 )'(8) (f-1)'(8) = -1/8 Calculate f - l (x) and state domain and range of f - l. Use interval notation. If needed enter inf for infinity or mint for -infinity. f-1(x) = Domain = (0,infinity) Range = (7,infinity) Calculate (f-1)'(8) from the formula for f -1(x) and check that it agrees with the result of part (B)
