DOMAIN AND RANGE

When it comes to statistics in the world of mathematics, physics, chemistry, these words are very commonly used. More often than not, they are used together.

A domain is used to refer to a set of numbers representing the independent variable while range refers to a set of numbers or values of the dependent variable.

As the names suggest domain is a dominant thus can exist independently. Range as it suggestively means is a spectrum of values that result dependent of the independent variable which is the domain

An example in mathematics:-

Let’s take a function like y=6+3x whereby x represents all set of values of the domain while y represents the range of values you are likely to get depending on the value of this means y cannot exist without the “x” value.

Using the same example, you may be given the domain “x”=-1, 2, 4. on calculations using the function y=6+3x, then “y”=3, 12, 18.this interprets when represented on a graph that the range of the functional domain is 3 to 18.this shows there is a value of numbers between these two values so depending on the x value then you can get any number between these two values.
