Number 7 is all real numbers for domain and range because the line has arrows which means it has a continuous x and y. For number 8 the domain is -5 to 3 because that is the leftest and rightest point. The range is -3 to 5 because it is the most bottom and top part of the graph. Hope this helps. By the way I did not put the answer with greater or less signs because I saw you did it different then me so just plug these numbers in. Hope this helps.
