Final answer:
The graph that represents the value of Jason's car after x years is a decreasing exponential function. The equation for the value of the car after x years is y = 12000(0.88)^x. The horizontal asymptote of the graph is y = 0.
Step-by-step explanation:
The graph that represents the value of Jason's car after x years is a decreasing exponential function. The value decreases by 12% every year, which means it is multiplied by 0.88. The equation for the value of the car after x years is y = 12000(0.88)^x. The horizontal asymptote of the graph is y = 0, meaning that the value of the car approaches zero as x increases.
