1.Let f:(−1,1)→Rf: (-1, 1) \to \mathbb{R}f:(−1,1)→R be a function defined by f(x)=max{−∣x∣,−1−x2}f(x) = \max\{-|x|, -\sqrt{1 - x^2}\}f(x)=max{−∣x∣,−1−x2}. If KKK be the set of all points at which fff is not differentiable, then KKK has exactly:Login to continueOnly logged in users canattempt or see the solution.
