How To Find Domain And Range Of A Graph Using Set Notation

To write the domain and range of a graph using set builder notation.

How to find domain and range of a graph using set notation. I review the warm up in the video below. Keep in mind that if the graph continues beyond the portion of the graph we can see the domain and range may be greater than the visible values. 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 latex x latex axis.

The range is all the values of the graph from down to up. Another way to identify the domain and range of functions is by using graphs. Another way to identify the domain and range of functions is by using graphs.

I use it to access their prior knowledge of inequalities or refresh their memory if necessary. The points 3 2 and 4 2 are on the graph in a which means that your domain should actually be x in 3 4 in interval notation to indicate that x 3 and x 4 are included. 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.

We can also use inequalities or other statements that might define sets of values or data to describe the behavior of the variable in set builder notation for example latex left x 10 le x 30 right latex describes the behavior of latex x latex in set builder notation. When looking at a graph the domain is all the values of the graph from left to right. Given a function in function notation form identify the domain and range using set notation interval notation or a verbal description as appropriate.

In the previous examples we used inequalities and lists to describe the domain of functions. The domain is all x values or inputs of a function and the range is all y values or outputs of a function. The range is the set of possible output values which are shown on the y axis.
