I was thinking about taking the limit and show that it is equal to $0$ such as … Webb22 mars 2016 · Explanation: To show that f (x) = x is continuous at 0, show that lim x→0 x = 0 = 0. Use ε −δ if required, or use the piecewise definition of absolute value. f (x) = x = {x if x ≥ 0 −x if x < 0 So, lim x→0+ x = lim x→0+ x = 0 and lim x→0− x = lim x→0− ( − x) = 0. Therefore, lim x→0 x = 0 which is, of course equal to f (0).
