In this problem there will be two domain and ranges because of the hole. The domain is (-∞,1) and (1,∞) The range is (-∞,2) and (2,∞)
Because both the X and Y values go to infinity they both have the ∞ and a ( or ). Since on the x-plane where the whole is, because it is an open hole so the exact point is not definite the notation is 1 with a ( or ). Then, its the same on the Y-plane because the hole is at 2 and because it is a whole it is notated with a ( or ).

The domain is [-4,0] and the range is [-3,0]
Because the x-values farthest left and right are -4 and 0 that is the domain and it is notated with [ or ] because it stops at those points.
Because the Y-values farthest up and down are -3 and 0 that is the range and it is also notated with [ or ] because it stops at those points.
