.3 2. Let f(a) = + 4.x (a) (10 marks) Find the arclength of the graph of f between the points (1/2, 13/12) and (1, 7/12). (b) (5 marks) What is the corresponding arclength for the graph of g(x) = (2 - 100)3 + 3 4(x - 100) between the same two points? 87-3 (c) (2 marks) What is the corresponding arclength for the graph of h(x) = 6 16x between x = 1/4 and x = 1/2? (Hint: what is f (2x)?)
