The ratio of consecutive values is not constant. therefore, it is not an exponential function. (Note that the difference of consecutive values is constant. therefore, this is a linear function.)

The exponential growth models describe the population of the indicated country, A, in millions, t years after 2006. Canada

use this information to determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. By 2009, the models indicate that Canada's population will exceed Uganda's by approximately 2.8 million.

A researcher is trying to determine the doubling time of a population of the bacterium Giardia lamblia. He starts a culture in a nutrient solution and estimates the bacteria count every four hours. His data are shown in the table. Use a graphing calculator to find an exponential curve f(t)=a⋅bt that models the bacteria population t hours later.
