The function f : [0, ∞) → R defined by f(x) = √ x is continuous on [0, ∞) To prove that f is continuous at c > 0, we note that for 0 ≤ x < ∞, f(x) − f(c) = \ \ √ x −

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

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 (−∞,∞)

(I) There exists a δ0 > 0 such that f(x) is defined for all x ∈ (a − δ0,a + δ0) (II) For each ǫ > 0 there Let f(x) = x for all x ∈ R Use Definition 6 1 2 to prove that f is continuous function f(x)=1/x is continuous on the interval (0, +∞) Solution
