Work Step by Step
In order to find the depreciated value of the machine in 7 years, we must find the y-coordinate that is associated with x=7 years. Looking at the graph, y=3.5 when x=7, where y is measured in thousands of dollars. Therefore, the depreciated value of the machine in 7 years is $3500. In other words, the copy machine loses half of its value in 7 years.
