Question

what is the verbal description for domain and range? what is the set notation for the domain and range?

Answer 1

The domain of a function is defined as the set of all the possible x-values the function can evaluate.

Similarly, the range of a function is the set of all the y-values the function can take.

From the graph, the domain and the range of the function are:

`\begin{gathered} D:\lbrace-3,-2,-1,0,1,2,3\rbrace \\ \\ R:\lbrace2,3,4,5\rbrace \end{gathered}`
