## How do you find the absolute minimum and maximum values of a function?

Finding the Absolute Extrema

- Find all critical numbers of f within the interval [a, b].
- Plug in each critical number from step 1 into the function f(x).
- Plug in the endpoints, a and b, into the function f(x).
- The largest value is the absolute maximum, and the smallest value is the absolute minimum.

### How do you find local and absolute maximum and minimum?

The y- coordinates (output) at the highest and lowest points are called the absolute maximum and absolute minimum, respectively. To locate absolute maxima and minima from a graph, we need to observe the graph to determine where the graph attains it highest and lowest points on the domain of the function. See Figure 10.

#### What functions have an absolute maximum or absolute minimum?

A continuous function over a closed, bounded interval has an absolute maximum and an absolute minimum. Each extremum occurs at a critical point or an endpoint.

**What are local maximum and minimum values of a function?**

A function f has a local maximum or relative maximum at a point xo if the values f(x) of f for x ‘near’ xo are all less than f(xo). Thus, the graph of f near xo has a peak at xo. A function f has a local minimum or relative minimum at a point xo if the values f(x) of f for x ‘near’ xo are all greater than f(xo).

**Is local maximum the same as absolute maximum?**

An absolute maximum occurs at the x value where the function is the biggest, while a local maximum occurs at an x value if the function is bigger there than points around it (i.e. an open interval around it).

## What is the absolute maximum value of a function?

An absolute maximum point is a point where the function obtains its greatest possible value. Similarly, an absolute minimum point is a point where the function obtains its least possible value.

### What is the difference between absolute maximum and local maximum?

The maximum or minimum over the entire function is called an “Absolute” or “Global” maximum or minimum. There is only one global maximum (and one global minimum) but there can be more than one local maximum or minimum. Assuming this function continues downwards to left or right: The Global Maximum is about 3.7.

#### What is the difference between local and absolute extrema?

An absolute extrema is the maximum or minimum value found throughout the interval of a function. A local extrema is the maximum or minimum value found within a specified interval of the function.

**What are local maximum values?**

A local maximum point on a function is a point (x,y) on the graph of the function whose y coordinate is larger than all other y coordinates on the graph at points “close to” (x,y).

**What is the difference between maximum and local maximum?**

Maximum is the greatest element in a set or a range of a function. Global maximum is the greatest value among the overall elements of a set or values of a function. Local maximum is the greatest element in a subset or a given range of a function.
