Question

A pond started with two bass, but the population tripled every year (t)
Write an equation for this story.

Answer 1

Answer:

$y=2(3^t)$

Step-by-step explanation:

In this problem we have a exponential function of the form

$y=a(b^t)$

where

y---> is the population of bass

t ----> the number of years

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate of change

b=(1+r)

we have

$a=2$

$r=200\%=200/100=2$

so

$b=(1+2)=3$

substitute

$y=2(3^t)$

Is a exponential growth function
