We need to find the domain and range of the given function.
Empty circle = we don't take the value
When we use [] on an interval, it means that we take the end values.
When we use () on an interval, it means that we don't take the end values.
To find the domain, we need to look at the x-axis. The values that the graph can take. In this case, the graph on the x-axis starts at x=-5 and the end is x=3.
However, we have an empty circle at the beginning and at the end.
Therefore, the domain is the interval (-5,3)
To find the range, we need to look over the y-axis. This means the values that the graph of the function f can take on the y axis. Then, the range is the interval (-4,4).
