Given:
The graph of a function.
To find:
The range of the graph.
Solution:
Domain: The set of input values are called domain.
Range: The set of output values are called range.
From the given graph it is clear that the function is defined for all real values of x but the output values are lie between
.
So, the range of the graph is
![Range=\{y|-4\leq y](/tpl/images/1232/0128/28c5e.png)
The interval notation of the range is:
![Range=[-4,\infty)](/tpl/images/1232/0128/7ac15.png)
Therefore, the correct option is A.
