# Please I need help ASAP The answer choices $1,300 .$1,500  .  $3,300 .$4,300 .   $4800/1 copier . -$500/1 year .   V(x) = −500x + 4800 .    V(x) = 500x + 4800A copier purchased new for $4,800 depreciates in value$500 each year. 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 .

Accepted Solution

A:
1. The function that models this equation is: Since the value V (x) of the copier depreciates over time, hence the 500 must be negative, therefore the equation: V(x) = −500x + 4800   2. The rate of change for the function is: The rate of change is also equivalent to the slope of the equation, in this case the slope is equal to: -$500/1 year 3. The model predicts that the value of the copier after 3 years will be: Substituting the value of x = 3 to the function gives us: V(x) = −500 (3) + 4800 V(x) =$3,300   4. The model predicts that the value of the copier after 7 years will be: Substituting the value of x = 7 to the function gives us: V(x) = −500 (7) + 4800 V(x) = \$1,300
