We can observe that the graph extends horizontally from displaystyle -5−5 to the right without bound, so the domain is displaystyle left[-5,infty ight)[−5,∞). The vertical extent of the graph is all range values displaystyle 55 and below, so the range is displaystyle left(mathrm{-infty },5 ight](−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.
