Question

At the beginning of an environmental study, a forest covered an area of 1500 km^2. Since then, this area has decreased by 4.25% each year. Let t be the number of years since the start of the study. Let y be the area that the forest covers in km^2. Write an exponential function showing the relationship between y and t.

Answer 1

y = 1500 * 0.9575^t

Explanation:

Where 0.9575 is equal to 1 - 0.0425, which represents a decrease of 4.25% each year.
