Which of the following describes an exponential growth?

a. a population grows 5% each year
b. the area of a square of side s
c. the cost of an apple per kilogram
d. the height of a person with respect to his age.

Is A the right answer?

agree

Yes, option A is the correct answer. An exponential growth occurs when a quantity increases at a constant percentage rate over a fixed interval of time. In this case, if a population grows at a rate of 5% each year, it demonstrates exponential growth because the population is increasing by a fixed percentage (5%) every year.
