Problem 162 of 7
Choose whether The depreciation of a car's value by 12% each year. is better modeled by a quadratic or exponential function.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
distinguish area/acceleration/turning-point behavior from percent change.
Hidden until you reveal it.
Context must clearly indicate quadratic structure or exponential percent/multiplier structure.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Look for products, area, acceleration, or turning-point behavior for quadratic models.
2. Look for repeated percent change or repeated multiplication for exponential models.
3. Choose the model type and justify it from context.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Choosing based only on whether numbers are large or small.
