## Relative Maximum

### In mathematics, a relative maximum refers to a point on a graph where the function reaches its highest value within a specific region

In mathematics, a relative maximum refers to a point on a graph where the function reaches its highest value within a specific region. To understand the concept further, let’s consider a function f(x) defined on an interval [a, b].

A point x = c is said to be a relative maximum if there exists a neighborhood around c such that f(c) is the highest value of the function within that neighborhood. In other words, if you draw a small enough interval around c, the value of f(x) at c is greater than or equal to the values of f(x) for all other points within that interval.

To determine if a point is a relative maximum, we typically look at the values of the function in the vicinity of the point. There may be several relative maxima within a given interval.

To find relative maxima, we follow these steps:

1. Find the critical points: These are the points where the derivative of the function is zero or undefined. To find critical points, we calculate f'(x) and solve the equation f'(x) = 0. The values of x obtained are the critical points.

2. Check the behavior of the function around the critical points: We examine the values of the function to the left and right of each critical point. We compare the values to determine if the critical point is a relative maximum. If the values increase before and decrease after the critical point, then it is a relative maximum.

It’s important to note that a relative maximum can occur at an endpoint of an interval as well, where the function may not be defined beyond that point.

Overall, understanding relative maxima helps us analyze the behavior of a function within a particular region and identify its highest points.
