Answer: f(x)=200•(0.85)^x
Step-by-step explanation:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.
The length I’m guessing is either 2 because 7 x 2 = 14 or it’s 7 because 7 + 7 = 14. But I would go with 2.
I believe that the correct answer will be that 1
