The graph is symmetric about the y-axis, indicating that the function is an even function. Therefore, the range will be the same as the domain of the function. 
From the graph, we can see that the domain is approximately [-5,4] and the range is approximately [-3,3]. 
Option (C) is the only choice that matches this domain and range.
