-1,-2,-3,-4 and I can go on now we wanna graph all of the Xs that are less than 4 but we're not including 4 it's not less or equal than 4 it's less than 4 and to show that we're not including 4 what we're going to do is that we're going to draw a circle around 4 so this shows us that we're not including 4 if we were including 4
