Question

Which exponential function models how much a $52,500 car depreciates at 9%
each year, where y is the car value and x is the number of years? (^ means
exponent)

Answer 1

Answer:

y = 52500(.91)^x

Step-by-step explanation:

Exponential functions are written y = ab^x where a is the starting point and b is the common ratio. We know the initial worth is 52500 and each year the worth decreases 9% of the original year, making it work 91% of the previous value.
