Final answer:
The growth factor of the exponential growth equation y = 40,000(1.05) is 1.05, and the percent of increase is 5%.
Step-by-step explanation:
Exponential growth is a type of population growth where the rate of growth is constant. In the given equation y = 40,000(1.05), the growth factor is the number that is multiplied to the initial population to calculate the final population. In this case, the growth factor is 1.05. The percent of increase can be calculated by subtracting 1 from the growth factor, and then multiplying the result by 100. So in this case, the percent of increase is (1.05 - 1) * 100 = 5%.
