Really nice explanition. However in this general form the statement is not correct. If we consider A = {0}, c = 0 and f : A -> R with f(0) = 0, we have that the limit of f(x) as x approaches zero is ANY value. Proof: Let Epsilon > 0 and chosse delta = 1. Now there is no x in A such that 0 < |x-0| = |x| < 1 = delta, because 0 is the only value in A. Therefore the implication of the epsilon-delta defintion is true for any value of L. (A -> B is true if A is false). You can fix this problem by assuming that c is in the interior of A.

I still dont understand why we take the delta to be the minimum ?

Because if you take delta to be max that is suppose if delta1 is max then delta will be equal to delta1 also delta2
