Apublic pool opened for the summer. a total of 246 people came swimming over the first 3 days it was open. on the first day, 79 came to swim. on the second day, 104 people swam. how many people swam on the third day?

Because this graph does not show two arrows pointing away from each other, this becomes an 'and' inequality, which cancels out options A and B. We can also see that the line doesn't go any lower than -2 and doesn't go any higher than 3, so that means x is greater than or equal to -2 and less than or equal to 3. Numerically, this would be or option D.
