Question: Consider a function f : R R; let us say that Limmxa f(x) = L if e > 0 such that > 0, |x a|

Consider a function f : R R; let us say that Limmxa f(x) = L if e > 0 such that > 0, |x a| < = |f(x) L| < e

Let f(x) = x for all x R. Does Limmxa f(x) exist for any a? If so, what can you take e to be, and what is L?

(b) Let f(x) = 1 for all x R. Does Limmxa f(x) exist for any a? If so, If so, what can you take e to be, and what is L?
