 Question 135252: Can someone help me please? Express the interval in set-builder notation and graph the interval on a number line. [-∞,5/3] If you can not graph that is ok. ThanksAnswer by stanbon(57347)   (Show Source): You can put this solution on YOUR website!Express the interval in set-builder notation and graph the interval on a number line. [-∞,5/3] ------------------------- Comment: You never have a bracket ([ or ]) where inf or -inf are involved in the interval. The interval is always open to -inf or +inf. [-inf, 5/3] This should be (-inf,5/3] which is set-builder notation is {x|x <= (5/3)} ----------------- The graph consists of a solid circle at 5/3 and an arrow extending to the left from 5/3. ------------------ Cheers, Stan H.
