Consider the following graph.
Determine the domain and range of the graph. Remember that repeated values in a set only need to be included once. 1-5,7-1,
1-2, -1,5
The domain of a graph represents all the possible input values, or x-values, for the graph. In this case, the x-values are given as 1, 2, -1, and 5. So, the domain is {1, 2, -1, 5}.
The range of a graph represents all the possible output values, or y-values, for the graph. In this case, the y-values are given as 5, 7, 2, -1. So, the range is {5, 7, 2, -1}.
