Use Exercises 64 and 65 to prove the following assertions for all x ≥ 0 (each assertion follows from the previous one):
Data From Exercise 64
Prove that if ƒ(0) = g(0) and ƒ'(x) ≤ g'(x) for x ≥ 0, then ƒ(x) ≤ g(x) for all x ≥ 0. Show that the function given by y = ƒ(x) − g(x) is nonincreasing.
Data From Exercise 65
