A veterinarian depreciates a $10,000 X-ray machine. He estimates that the resale value V(t) (in $) after t years is 90% of its value from the previous year. Therefore, the resale value can be approximated by V(t) = 10,000(0.9)t. Requried:
a. Find the resale value after 4 yr.
b. If the veterinarian wants to sell his practice 8 yr after the X-ray machine was purchased, how much is the machine worth? Round to the nearest $100.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
