Answer

Domain: (-infinity, -2]U[2, infinity) Range: (-infinity, infinity)

Work Step by Step

The graph extends from x= -2 infinitely to the left and from x=2 infinitely to the right, with nothing in between, so the domain is from -infinity to -2 and 2 to infinity The graph extends infinitely both upwards and downwards, so the range is from negative to positive infinity
