Technology required. A function f gives the number of stray cats in a town t years since
8090 [49]

This means that the number of stray cats in a town when the town started the animal control program is 729.

<h3>Exponential function</h3>

An exponential function is given by:

y = abˣ

Let y, x are variables, a is the initial value and b is the multiplication factor.

Where f is the number of stray cats in a town t years since the town started an animal control program.

Since f(t) = 729(\frac{1}{3} )^t

f(0) = 729(1/3)° = 729

This means that the number of stray cats in a town when the town started the animal control program is 729.
