A bacterial culture began with 10,000 bacteria. The graph below shows the rate (measured in bacteria per hour) at which the number of bacteria grew at each moment in time (measured in hours) after the culture was first observed. The rate fluctuated because the culture's environment fluctuated.

(a) Based on the graph, describe the rate of change of bacteria population during the 3.5 hour time period.

(b) When is the number of bacteria growing? Decreasing? Explain how you know.

(c) When is the number of bacteria at its highest? Lowest? Explain how you know.
