If f is continuous on [a, b], differentiable on (a, b), and f(a) = f(b), then there is a real number c in (a, b) for which f′(c) = 0. More generally, suppose f is continuous on [a, b] and differentiable on (a, b). Let g(x) = f(x) − f(b) − f(a) b − a (x − a) − f(a).

Increasing and Decreasing Functions. Let y = f (x) be a differentiable function (whose derivative exists at all points in the domain) in an interval x = (a,b). If for any two points x 1 and x 2 in the interval x such that x 1 < x 2, there holds an inequality f (x 1 ) ≤ f (x 2 ); then the function f (x) is called increasing in this interval.First, take the derivative: Set equal to 0 and solve: Now test values on all sides of these to find when the function is positive, and therefore increasing. I will test the values of -6, 0, and 2. Since the values that are positive is when x=-6 and 2, the interval is increasing on the intervals that include these values.Calculus.

And the function is decreasing on any interval in which the derivative is negative. How do we determine the intervals? …Take the derivative of the function. Find the critical values (solve for f ' ( x) = 0) These give us our intervals. Now, choose a value that lies in each of these intervals, and plug them into the derivative. If the value is positive, then that interval is increasing. If the value is negative, then that interval is decreasing.

If the slope (or derivative) is positive, the function is increasing at that point. If it’s negative, the function is decreasing. So to find intervals of a function that are either decreasing or increasing, take the derivative and plug in a few values.

In fact it can be easily proven that any continuous function defined on a closed interval and monotonic on the open interval with the same endpoints is also monotonic on the closed interval. This shows that it isn't incorrect to exclude the endpoints, but it consists in a loss of information if the conditions are actually met.

A function is said to be decreasing (not strictly, in the broad sense) if for all x1 <x2,f(x1)≥f(x2) x 1 < x 2, f ( x 1) ≥ f ( x 2) Example: The function f(x)= −x+1 f ( x) = − x + 1 is decreasing over its whole domain of definition R R, hense its monotony. The decrease of a function can also be defined over an interval. Solution: \ (\begin {array} {l} \frac {dy} {dx} = 3x^2 \geq 0\end {array} \) So, it is an increasing function.
