Question

Kevin is observing the population of the fish he put into a pond. He built a pond and populated it with 500 fish. The population of the fish doubles every year.

Use x to represent the number of years and y to represent the population of the fish.

Answer 1

y = 500
`(2)^(x)`

Explanation:

just took the test :D

Answer 2

Here we will use exponential form, which is

`y = y_(0) e^(kt)`

Initial value, y0 = 500

Double of 500 = 1000

`1000 = 500e^(k*1)`

`2 = e^k`

`k= ln (2)`

Required equation is
