Chapter 6.2, Problem 2E

To determine

To write: The decay factor in the exponential decay function $y=a\left(1-r\right)$ .

Answer to Problem 2E

The decay factor in the exponential decay function $y=a\left(1-r\right)$ is $r$ .

Explanation of Solution

The exponential decay function is the pattern in which a specific quantity decays by a fixed percent in terms of regular intervals of time.

The exponential decay function can be depicted as $y\left(t\right)=a{\left(1-r\right)}^t$ .

The value of $a$ represents the initial amount, $r$ represents the decay factor and $t$ represents the number of regular intervals of time.

Therefore, the decay factor in the exponential decay function $y=a\left(1-r\right)$ is $r$ .
