A copier purchased new for $4,800 depreciates in value $500 each year.

Question

1. The function that models this equation is _

2. The rate of change for the function is _

3. The model predicts that the value of the copier after 3 years will be _

4. The model predicts that the value of the copier after 7 years will be _

Word bank
$3,300
$1,500
V(x) = 500x + 4800
$4800/1 copier
V(x) = -500x + 4800
$1,300
-$500/1 year
$4,300

(Only use one of the choices per question)

Answer 1

1. The function that models this equation is V(x) = -500x + 4800
2. The rate of change for the function is -$500/1 year
3. The model predicts that the value of the copier after 3 years will be V(3) = -500(3) + 4800 = $3,300
4. The model predicts that the value of the copier after 7 years will be V(7) = -500(7) + 4800 = $1,500
