A new car worth $26,000 is depreciating in value by $2000 per year. Complete parts (a) through (c).
a. Write a formula that models the car's value, y, in dollars, after x years.
b. Use the formula from part (a) to determine after how many years the car's value will be $16,000.
c. Graph the formula from part (a) in the first quadrant of a rectangular coordinate system. Then, show your solution
to part (b) on the graph.
