To determine

To calculate: The number of years after which the value of cars becomes $\$6,000$, when the function shown in the following table and graph represents the depreciation in the value (in dollars) of a used car whose initial value was $\$15,000$, when the value of the car is decreasing at the rate of $\$2,000$ per year.

Time(years)	Value $\left(\$\right)$
$0$	$\$15,000$
$1$	$\$13,000$
$2$	$\$11,000$
$3$	$\$9,000$
$4$	$\$7,000$
$5$	$\$5,000$

The graph is,
