2. (Lecture 13) Let f : R + R be defined by : x2 f(a): X +0 x = 0 -1 (a) Prove that f is not continuous at 0 by directly verifying the negation of the ε – o definition of continuity at 0. (b) Prove that f is not continuous at 0 using a sequential continuity argument (i.e., by using the Corollary from Lecture 13).
