Answer:
Domain is
Average rate of change of bacteria per minute is -3333.33.
Step-by-step explanation:
Domain is the possible values of .
From the graph, it's clear that the values ranges from 0 to 18 as the end points of the graph are
and
So, domain of the function is .
Now, average rate of change is negative as there is bacteria decay.
Average rate of change is given as the negative ratio of y intercept to the x intercept.
Here, x-intercept is 18 and y-intercept is 60000.
So, average rate of change is given as,
Therefore, average rate of change of bacteria per minute is -3333.33.
