Which statement compares the limit as x approaches –4 for the two graphs? In both graph I and graph II, the limit is 5. In both
graph I and graph II, the limit does not exist. In graph I, the limit does not exist, but in graph II, the limit is 5. In graph I, the limit is 8, but in graph II, the limit does not exist. ANSWER: A
(Thanks) it's A because the limit is in the same place on both graphs. The filled-in dot doesn't affect the limit at all, it just means the "real" value of x=-4 is 8, but the "limit" is still at 5 either way.
You need to covert the decimal to a fraction and then if they have the same denominator then compare by the numerator if they don’t the same denominator then change so they do have one then compare
