Exponential Functions 1.18 - Solution

arrow_back Return to Exponential Functions

We can model the value of the car by using the exponential decay function. The function can be used to find the value of the car after time period, where is the initial value of the car and is the percent of decrease per time period. For our model, and Now that we have the function, we can graph the function showing the value of the car for the first twenty years. To do so, we will first make a table of values.

Let's now plot and connect the points and with a smooth curve.
