Let a and b be real numbers with a < b. Suppose that f : [a, b] −→ R
is continuous and that f is differentiable on the open subinterval (a, b). Use
the Mean Value Theorem to show that if f
′ > 0 on (a, b) then f is strictly
increasing on [a, b].

Write down any three specific nonzero vectors u, v, w from R
3 and any
two specific nonzero scalars a, b from R. Compute u+v, aw, b(v+w), (a+b)u,
u + v + w, abw, and the additive inverse to u.
