Quizplus · Accepted Answer

The one-year growth factor is the ratio of the function value after one year to the function value at the beginning of the year. From the graph, we can see that the function value at the beginning of the year is approximately 50, and the function value after one year is approximately 90. Thus, the one-year growth factor is 90/50 = 1.8.
