Question

E. coli Growth A strain of E. coli Beu 397-recA441 is placed
into a nutrient broth at 30° Celsius and allowed to grow. The
data shown in the table are collected. The population is
measured in grams and the time in hours. Since population P
depends on time t, and each input corresponds to exactly
one output, we can say that population is a function of time.
Thus P1t2 represents the population at time t.(a) Find the average rate of change of the population from
0 to 2.5 hours.
(b) Find the average rate of change of the population from
4.5 to 6 hours.
(c) What is happening to the average rate of change as time
passes?
