Domain Range Math Is Fun

Graphs of domain and range of functions.

Domain range math is fun. When the function f x x2 is given the values x 1 2 3 then the domain is simply those values 1 2 3 domain range and codomain. The lowest value is 5 and the highest is 3616 so the range is 3616 5 3611. This post clarifies what each of those terms mean.

All the values that go into a function. A simple function like f x x 2 can have the domain what goes in of just the counting numbers 1 2 3 and the range will then be the set 1 4 9. The range is the set of possible output values shown on the y axis.

The output values are called the range. Domain range and codomain. Domain function range.

The domain of a graph consists of all the input values shown on the x axis. The domain refers to the set of possible input values. Before we start talking about domain and range lets quickly recap what a function is.

You cannot have the value x 3. Another way to identify the domain and range of functions is by using graphs. Domain of a function.

The domain and range of a function is all the possible values of the independent variable x for which y is defined. The range of a function is all the possible values of the dependent variable y. A function relates each element of a set with exactly one element of another set possibly the same set.
