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