Calculus:

Problem 13. (1 point) Consider the function f(x) = vx - 5. (A) Find f '(5) = (B) Use Theorem 7, page 156 of the Stewart Essential Calculus textbook to find (f )'(5) (f 1)'(5) = (C) Calculate f 1(x) and state domain and range of f . Use interval notation. If needed enter inffor co or -inffor -co. f (x) = Domain = Range = Calculate (f )'(5) from the formula for f () and check that it agrees with the result of part (B)
