Answer:
(-5, 2)
Explanation:
Often, an arrow at the end of a graph indicates the graph extends to infinity in both the x- and y-directions. However, when the graph has a vertical asymptote at each end of its domain, it would have an arrow pointing upward, but not sideways.
It is difficult to tell from this graph what the intention is. It appears that there may be vertical asymptotes at x = -5 and at x = 2. If that is the case, then the domain is restricted to the interval ...
-5 < x < 2
(-5, 2) in interval notation
