Question A1: Show that if p and q are positive integers, and (p/q)2 < 2, then there is a real number r such that Question A2: The functions f (x) = and = are inverse functions, provided the domain of each is taken to be the non-negative real numbers. (a) Determine the value of f' (b) Compute g' (9)? Question A3: 34, what is the value of f' Consider the function f (x) = tan@). If f (x) = Hint: The numbers 3, 4, and 5 form a pythagorean triple.
