Let’s look at the table of values:
t
y
0 800
5 1855.8
10 3606.8
To the nearest whole number, the deer population after 10 years is 3,607.
In Part (c), we’ll need to graph a horizontal line at y =5, 000 and find the intersection.

(13.54, 5000)
2,000
5 10 15 20 25 30
To the nearest 10th, it takes about 13.5 years for the deer population to reach
5,000.
