Furthermore, 1 is the smallest number which is greater … WebNote. For a given sequence of functionsfn, if for all x ∈ E the sequence of numbers {fn(x)} converges, then we can define f(x) = limn→∞ fn(x) with domain E. Are there properties of the fn functions which are shared by the limit function f? Question 1. If fn is continuous for all n ∈ N, is limn→∞ fn continuous? Answer 1. NO!
