Answer 9

to me, the graph of the function limited by the time the experience happen. let say the x-axis is the time and it is shown every 1minute, of course the time is from 0 to infinitive (all positive number). and the y-axis is the number of the bacteria. However, the experience happens from 9: 05 to 9:55. That means the function's domain is limited from 5<=x <= 55
