In this problem we will consider what happens when we reverse the order of the quantifiers in the definition of continuous. We say that a function f : R → R is flat at the point a ∈ R if (and only if) it satisfies the following condition: ∃δ > 0, ∀ > 0, |x − a| < δ −→ |f(x) − f(a)| < . (The universe for all variables is R.) Prove that for all m, b ∈ R, if f(x) = mx + b is flat at 0, then m = 0
