Range Definition Math
Essentially the range tells us how spread apart a group of numbers is.
Range definition math. Domain and range the domain and range of a function is all the possible values of the independent variable x for which y is defined. In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6. Range definition the range of a function is the set of outputs the function achieves when it is applied to its whole set of outputs. In a set of data the range is the difference between the greatest and smallest value.
As a function table and as a set of coordinates. Range can also mean all the output values of a function. The range of a function is all the possible values of the dependent variable y. So the range is 9 3 6.
The image of f x x 2 is the set of all non negative real numbers if the domain of the function is the set of all real numbers. It is that simple. The difference between the lowest and highest values. In math range is a statistical measurement of dispersion or how much a given data set is stretched out from smallest to largest.
This lesson will define and describe how to determine the range and will also give some examples. Range is one of four simple tools of statistics. How do i find range. The range is the difference between the lowest and highest numbers in a data set.
Range of a function mathematics the set of values of the dependent variable for which a function is defined. The example below shows two different ways that a function can be represented. Range statistics more. The range of a function is the set of values that are produced by that function.
