Q. There are

170

deer on a reservation. The deer population is increasing at a rate of

30\%

per year. Write a function that gives the deer population

P(t)

on the reservation

t

years from now.

Identify population and growth rate: Identify the initial population ( $a$ ) and the growth rate ( $r$ ).
Calculate growth factor: Calculate the growth factor $b$ using the formula $b = 1 + r$ .
Write exponential function: Write the exponential function $P(t)$ that models the deer population after $t$ years.
