The range of a function is the possible y values, the function can take.
The range of the graphed function is [tex]\mathbf{-3 < y \le 3}[/tex]
From the question (see attachment for graph), we have the following observations
An open circle means > or <
A close circle means >= or <=
To link -3 to 3, we make use of less than and less than or equal to sign
So, the range of the function is:[tex]\mathbf{-3 < y \le 3}[/tex]
