Park rangers released 4 fish into a pond in year 0. Each year, there were three

times as many fish as the year before. How many fish were there after x

years? Write a function to represent this scenario.

Step-by-step explanation:

f (x) = 4 (3) with an exponent of x on the top.

Answer: y (x) = 4 (3) ∧x

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Park rangers released 4 fish into a pond in year 0. Each year, there were three times as many fish as the year before.

We have to apply the exponential growth expression:

y (x) = ab∧x

Where:

a = initial amount

b = growth factor

x = number of years

Replacing with the values given

y (x) = 4 (3) ∧x
