 Question 133354: Randolf bought a high-end computer system for \$4800. The system depreciates at the rate of 25% each year. Determine an exponential funciton 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. I understand how to get the exponential funciton but I am having difficulty with the table, expression and value.
