1. The function that models this equation is V(t) = 4800 - 500t, where V(t) represents the value of the copier after t years.
2. The rate of change for the function is -500, which represents the decrease in value per year.
3. Plugging in t = 3 into the function, we have V(3) = 4800 - 500(3) = 4800 - 1500 = $3300. Therefore, the model predicts that the value of the copier after 3 years will be $3300.
4. Plugging in t = 7 into the function, we have V(7) = 4800 - 500(7) = 4800 - 3500 = $1300. Therefore, the model predicts that the value of the copier after 7 years will be $1300.
A copier purchased new for $4,800 depreciates in value $500 each year.
