$Domain = (-\infty , \infty)$ $Range = (-\infty,2) \cup [1, \infty)$
We can see that the relation covers all the x-values, therefore its domain is $(-\infty , \infty)$ And we can see that the relation covers all y-values except the interval $[2,1)$, therefore its range is $(-\infty,2) \cup [1, \infty)$
