2. Below is the definition of continuity, which you'll see in lecture soon or have already seen in lecture. Part (a) below uses this
definition, but the strategy involved in proving (a) is something that we saw within a theorem on limits already.
Suppose EC R, f: E → R, and let co € E. Then f is continuous at ro iff for each e > 0 there is a > 0 such that if
x-xo| < 6 and x = E then f(x) - f(xo)| < €.
(a) Suppose ECR and f: E → R and to € E be an is an accumulation point of E (note that this is not required in the
definition, unlike in the definition of limit).
Prove that f is continuous at xo if and only if for any sequence {n}n that converges to co with In E E for each n, the
sequence {f(x)} = converges to f(xo).
