An exponential graph has Time in Years on the x axis and Enrollments on the y axis. A curve that rises from left to right begins at zero comma thirty and passes through twenty comma eighty.
Let's look over the options. Option A and option C would both be invalid; being a percentage and not a whole number, they would both cause the graph to slope downwards, decreasing. We can eliminate those two.
Options B and D are both positive. However, option B's 6% would slope a lot more sharply upwards. Remember that the graph goes by the year, not by every five years!
