Find the domain and range of a function defined by a graph Question
Use the graph of the function to find its domain and range. Write the domain and range in interval notation.

 domain (-2, 3]  range [-2, 2)

These are the x-values left to right the paretheses ( ) indicates "not equal to" a bracket [ ]

Step-by-step explanation:  Domains are the x-values left to right the parentheses ( ) indicates "not equal to" like the open circle on the graph;  a bracket [ ] means "and equal to" like the solid circke on the graphed line.

Range means the y-values, bottom to top (least to greatest in math lingo)
