The elephant population in Northwestern Namibia and Etosha National Park can be predicted by the expression 2,649(1.045)^b, where b is the number of years since 1995.

What does the value 2,649 represent?

A.) the predicted increase in the number of elephants in the region each year

B.) the predicted number of elephants in the region in 1995

C.) the year when the elephant population is predicted to stop increasing

D.) the percentage the elephant population is predicted to increase each year

What does the value 2,649 represent?

A.) the predicted increase in the number of elephants in the region each year

B.) the predicted number of elephants in the region in 1995

C.) the year when the elephant population is predicted to stop increasing

D.) the percentage the elephant population is predicted to increase each year

Combined estimates for Etosha National Park and the Northwestern Population

**The model for exponential growth or decay is:**

**y(t) = a × e^(kt)**

y(t) is the ending amount

a is the beginning amount

k is the rate of growth (when > 0) or decay (when < 0)

t is time

So, in the exponential expression 2,649(1.045)^b

2,649 would be the beginning amount, therefore

**B.) the predicted number of elephants in the region in 1995**
