Question 133242: Randolf bought a high-end computer system for $4800. The system depreciates at the rate of 25% each year.
a) Determine an exponential function to model the value of the system over time. You might use a table of values with columns for years, the expression for calculation for that year, and the value on that year to help you in your derivation.

Randolf bought a high-end computer system for $4800. The system depreciates at the rate of 25% each year.
a) Determine an exponential function to model the value of the system over time.
Value(x) = 4800*0.75^x
--------------------------
x is the number of years after the purchase of the computer system.
