Question

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.

Answer 1

Answer:

Step-by-step explanation:

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

Answer 2

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
