WebMar 8, 2024 · In calculus, increasing and decreasing functions are the functions for which the value of f (x) increases and decreases, respectively, with the increase in the value of x. To check the change in functions, you need to find the derivatives of such functions. If the value of the function increases with the value of x, then the function is positive. WebSolution: I have applied mean value theorem on the interval [ 0, x]. Then, f ( x) x = f ′ ( c), 0 < c < x. It is given that f ′ is an increasing function.
