  1. I

    f(x)=|x| satisfies Roll's theorem [-1,1]. State true or false with reasons.

    Free sample

    Answer: False

    Explanation

    To satisfy Rolle's Theorem on the interval [−1,1][-1, 1], a function f(x)f(x) must be continuous on the closed interval [−1,1][-1, 1] and strictly differentiable on the open interval (−1,1)(-1, 1). The given function f(x)=∣x∣f(x) = |x| is continuous everywhere, including on [−1,1][-1, 1]. However, we must check its differentiability at x=0x = 0, which lies within the open interval (−1,1)(-1, 1). The left-hand derivative at x=0x=0 is −1-1, and the right-hand derivative at x=0x=0 is 11. Because the left-hand and right-hand derivatives are not equal, f(x)=∣x∣f(x) = |x| is not differentiable at x=0x = 0. Since it fails the necessary condition of differentiability on the open interval, it does not satisfy Rolle's theorem.
