Use the graph to determine the domain and range. Then state whether the relation is a function.

What is the domain of the​ function?

Answer 1

[-2, 4]

Explanation:

The domain of a function is the set of all x-values a relation could possibly take on to have an output. This is represented by in the graph by having the line correspond to the x-value. From the graph shown we can see that x-values from -2 to 4 have a line corresponding to them, and the dots are closed meaning it is inclusive. This would be written as: [-2, 4]
