1. A 1993 Lexus costs $39,375 and the car depreciates during its first 7 years a total of 46%.
a.) Suppose the depreciation is exponential. Find a formula for the value of the car at time t.
Be sure to find the depreciation rate for ONE year…not seven.
b.) Suppose instead that the depreciation is linear. Find a formula for the value of the car at time t.
c.) If this were your car and you were trading it in after 4 years, which depreciation model would you prefer? (exponential or linear)
2.) Assume that f and g are exponential functions. Find an equation for each.
