Okay, we have a rabbit population, and that rabbit population is starting at 24 in 2011.
00:10
Now, when we write a function for this, we're going to start with that 24.
00:15
We're going to say 24, and we're going to have continuous multiplication by 2 because we double each year.
00:22
So we're going to put a 2 here, and then since it is repeated multiplication by 2, we need an exponent for our t.
00:30
And so this would be the number of rabbits r is equal to 24 times 2 to the t power.
00:39
Okay, now let's move on to part b now.
00:42
We want to approximate the amount of rabbits in 2018.
00:46
So since we're going from 2011 to 2018, we have seven years is equal to our t.
00:57
So we can say this is r is equal to 24 times 2.
01:02
To the seventh power.
01:06
And we'll set that equal to...
