Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.

Write an equation to model this situation.

Sagot :

This is an exponential function.

At year [tex]x[/tex], the number of rabbits would be as follows:

[tex]y=4e ^{(x*(In2))} [/tex]

Where x is the number of years
R=Number of rabbits

y=Years that have passed by { y ≥ 0 }

R=f(y) --> R is a function of y.
---------------------------------------------

Note that when:

y=0, R=4 ---> Point: (0, 4)

y=1, R=8 ---> Point (1, 8)

y=2, R=16 ---> Point (2, 16)

y=3, R=32 ---> Point (3, 32)

y=4, R=64 ---> Point (4, 64)

--------------------------------------------

So the equation you want is going to form a curved graph.

That equation is:

[tex]R={ 2 }^{ y+2 }[/tex]

*You can test out this function on any decent graphing software.
