Question

prove that a constant function is a differntaiable function​

Answer 1

Answer:

f/(x) < 0 on a<x<b, then f is decreasing on a ≤ x ≤ b. If f/(x) ≤ 0 on a<x<b, then f is nonincreasing on a ≤ x ≤ b. The Increasing Function Theorem has a cousin: The Constant Function Theorem Suppose that f is continuous on a ≤ x ≤ b and differentiable on a<x<b. If f/(x)=0ona <x<b, then f is constant on a ≤ x ≤ b.
