Determine if the function is differentiable

WebInformally, Rolle’s theorem states that if the outputs of a differentiable function f f are equal at the endpoints of an interval, then there must be an interior point c c where f ′ (c) = 0. f ′ (c) = 0. Figure 4.21 illustrates this theorem. WebFeb 17, 2024 · So for differentiability of the function at x = 1, we must have both (1) a + b = e (2) 1 + 2 a + b = e Solving this, we have a = − 1 and b = e + 1. So the function will be differentiable only for a = − 1 and b = e + 1. Hence, the option ( 2.) is correct.
