Proposition If g is continuous at c and f is continuous at g(c), then f ◦ g is continuous at c Example The function h(t) = cos(3t + 4) is continuous on (−∞,∞) since it is the composition of the functions g(t)=3t + 4 and f(t) = cos(t), both of which are continuous on (−∞,∞)

If f : (a, b) → R is defined on an open interval, then f is continuous To prove that f is continuous at c > 0, we note that for 0 ≤ x < ∞, lim n→∞ xn − yn = 0 and f(xn) − f(yn) ≥ ϵ0 for all n ∈ N Proof If f is not uniformly continuous, then
