The table show the value of a car as it relates to its age. A 2-column table with 5 rows. The first column is labeled age (years) with entries 0, 1, 2, 3, 4. The second column is labeled value (dollar sign) with entries 20,000; 18,000; 16,200; 14,580; 13,122.

Which statements describe the value of the car as a function of x, its age in years? Check all that apply.

The relationship is quadratic.
The relationship is exponential.
The domain is {x | x < 0}.
The range is {V | 0 V 20,000}.
The value, V, is represented by the equation
V = 20,000(0.9)x.
