(Step-by-Step) Let f and g be continuous functions on [a, b] such that f(a) g(a) and f(b) g(b). Prove that f(x o) = g(x o) for at least one x o in [a, b]. Hint:
Question:
Let f and g be continuous functions on [a, b] such that f(a)
g(a) and f(b)
g(b). Prove that f(x
o
) = g(x
o
) for at least one x
o
in [a, b].
Hint:
Let h = f - g. Then h is continuous and h(b)
0
h(a). Now apply the Intermediate Value theorem which states that
If f is a continuous real-valued function on the interval I, then f has the intermediate value property on I. Whenever a, b
I, a < b and y lies between f(a) and f(b) [i.e, f(a) < y < f(b) or f(b) < y < f(a)], there exists at least one x
(a, b) such that f(x) = y.
