Question

Jason estimates that his car loses 12% of its value every year. The initial value is 12,000. Which best describes the graph of the function that represents the value of the car after X years ?

Answer 1

The graph should describe exponential decay.

Explanation:

Every year, the car's value gets multiplied by 0.88, so the equation that gives the value, `y`, of the car after `x` years is

`y=12000(0.88)^x`

graph{12000(0.88)^x [-5, 20, -5000, 15000]}
