Use the graph to complete each statement. value of copier (in thousands of dollars) 1 3 time from date of purchase (years) 4 5 6 7 a. Complete the function, V(x) that gives the value, in thousands of dollars, x years from date of purchase: V(x)=x+- Hint: It will help to first complete these two statements: The value of the copier is decreasing at a rate of - thousand dollars per year. The value of the copier at the time of purchase was. b. Use the function you wrote in part (a) to determine the number of dollars that the copier is worth 2.5 years after purchase. Show your work. thousand dollars.
