(a) Let f, g, h be continuous on the interval [a, b]. If f(a) < g(a) < h(a) and f(b) > g(b) > h(b), then there exists c = [a, b] such that f(c) = g(c) = h(c).

Question
Determine whether the following statements are true or false. If true, provide a
proof; if false, provide a counterexample.
(a) Let f, g, h be continuous on the interval [a, b]. If f(a) < g(a) <h(a) and f(b) >
g(b) > h(b), then there exists c = [a, b] such that f(c) = g(c) = h(c).
(b) Suppose that f and g are continuous on R. If 0 ≤ f(x) < g(x) for all X, then
there is some x ER such that f(x)/g(x) is the maximum value of f/g.
(c) If f is continuous on R, then f is bounded.
