1.Let f(x)={max(∣x∣,x2),∣x∣≤28−2∣x∣,2<∣x∣≤4f(x) = \begin{cases} \max(|x|, x^2), & |x| \le 2 \\ 8 - 2|x|, & 2 < |x| \le 4 \end{cases}f(x)={max(∣x∣,x2),8−2∣x∣,∣x∣≤22<∣x∣≤4. Let SSS be the set of points in the interval (−4,4)(-4, 4)(−4,4) at which fff is not differentiable. Then SSSa.equals {−2,−1,0,1,2}\{-2, -1, 0, 1, 2\}{−2,−1,0,1,2}b.equals {−2,2}\{-2, 2\}{−2,2}c.is an empty setd.equals {−2,−1,1,2}\{-2, -1, 1, 2\}{−2,−1,1,2}Login to continueOnly logged in users canattempt or see the solution.
