Apply the evt and find extrema on a closed interval

👉 Learn how to find the extreme values of a function using the extreme value theorem. The extreme values of a function are the points/intervals where the graph is decreasing, increasing, or has an inflection point. A theorem which guarantees the existence of the maximum and minimum points of a function under some certain condition is called the extreme value theorem. The extreme value theorem states that if a function is continuous on a closed interval [a, b], then f(x) has both a maximum and a minimum value on [a, b].

To obtain the extreme values of a function on a closed interval using the extreme value theorem, first, we obtain the critical values of the function on the interval by finding the derivative and solving for x. Next, we evaluate the function at each of the critical values found, then we also evaluate the function at each endpoint of the interval. The least of these values is the minimum value and the greatest is the maximum value.
