Range In Math Example

If the lowest number is 3 and the highest number is 6 we solve for 6 3.

Range in math example. The range is the difference between the lowest and highest values. The example below shows two different ways that a function can be represented. We recommend that you do this too. The range of a function is the set of values that are produced by that function.

So the range is 9 3 6. Let s return to the example above y sqrt x 4. But there is no middle number because there are an even number of numbers. In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6.

The median is the middle number. The range of a function is all the possible values of the dependent variable y. You have two different ways to define range in math. A graph of a typical line such as the one shown below will extend.

The range of a set of data is the difference between the highest and lowest values in the set. If you re doing algebra or calculus the range is understood to be the set of possible results or output values of a function. In this example the numbers are already listed in numerical order so i don t have to rewrite the list. In 4 6 9 3 7 the lowest value is 3 and the highest is 9.

Range can also mean all the output values of a function. If you re doing statistics the range usually means the difference between the highest and lowest values in a set of data. We ordered the data from least to greatest before finding the range. In math it s very true that a picture is worth a thousand words.

In the problem above the set of data consists of 7 test scores. As a function table and as a set of coordinates. The range is the set of all possible output values commonly the variable y or sometimes expressed as f x which result from using a particular function. So in our example.

To calculate the range subtract the lowest number from the highest number. Because of this the median of the list will be the mean that is the usual average of the middle two values within the list. No matter what value of x we try we will always get a zero or positive value of y. The range of a simple linear function is almost always going to be all real numbers.

It is that simple. This lesson will define and describe how to determine the range and will also give some examples. We say the range in this case is y 0.
