And so here we're looking at the deer population from 2003 to 2007.
00:05
First, we want to figure out what the deer population is in 2003.
00:10
2003 is when t equals 0, so it's going to be right here at 30 ,000.
00:16
Now, if we want to find an exponential growth model for the population since 2003, we know that c is going to be our initial population, which is 30 ,000.
00:29
And then to find our growth rate, we're given another point.
00:33
So our growth rate, we take our term, divide it by the term before it, except we see here that we're jumping from an x value of 0 to 4, so we need to take the fourth root of it.
00:46
So our growth rate, or in this case, they call it a, is going to be 1 .08...
