Park rangers released 4 fish into the 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 senario

.

Step-by-step explanation:

Year 0 = 4 fishes

Since we are given that Each year, there were three times as many fish as the year before.

So , Year 1 = dishes

Year 2 = fishes

And so on

So, we can use formula of exponential growth :

where y is the number of fishes after x years

a is the initial amount

b is the growth factor

x is the number of years

a = 4

b = 3

Substitute the values in the formula :

To Check substitute x = 0

Park rangers released 4 fish into the pond in year 0

To Check substitute x = 1

Park rangers released 12 fish into the pond in year 1

Hence verified

Hence a function to represent this senario is .

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
