There is no restriction on the domain (x-values) as it is a line and is continuous for all real values of x, therefore the domain is:x=(-oo, +oo) or if you prefer: -oo≤x≤+ooSince there is no restriction on the domain also exists in this case no restriction of the variety.When x approaches -oo, and approaches -oo and as x approaches +oo, and approaches +oo, so the range is:y=(-oo, +oo) o-oo≤y≤+ooLastly could only say that the range and domain of both contain all real numbers.
