## What is the range of a list of numbers?

The “range” of a list a numbers is just the difference between the largest and smallest values..

## What is the range in math?

The range is the difference between the largest and smallest numbers. The midrange is the average of the largest and smallest number.

## What is the range of this function?

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.

## How do you find the range?

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.

## How do you express domain and range?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

## How do you interpret a range?

Interpretation. Use the range to understand the amount of dispersion in the data. A large range value indicates greater dispersion in the data. A small range value indicates that there is less dispersion in the data.

## Is Range always positive?

The range of a function is the set of all possible values it can produce. No matter what value we give to x, the function is always positive: If x is 2, then the function returns x squared or 4.

## Is output values domain or range?

When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.

## Can a non function have a domain and range?

Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements “used” by the relation or function constitute the range.
