Question

In 1980, the population of Arizona was 2,718,215. Each year, the

population increased by 3%. Let 1980 be year
a. Linear, Exponential, or Neither?

Answer 1

Exponential. You can see that the first year the population will grow by 3% of 2,718,215. However, the second year it will grow by 3% of the new value, which is going to be a greater value than the year prior. Since the definition of exponential is growing by more and more each time, it will be exponential.
