Mathematic Models - assignment

Maths Applied course assignment, I can't remember what it is im doing is called but you should get the drift.

Basically given a table with values and prepare a screen plot of data on calculator. All good, from there I have to find a suitable equation. I sat for about 2 hours trying to figure it out, and no luck.

2. Certain farmers in country Victoria had wind turbines installed for power generation. Properties in the area were valued every two months after the first wind turbines were installed. The average land value per hectare in the area was found to be as follows.

Months after the wind

turbines' installation (t):

0

2

4

6

8

10

Average land value per hectare ($) (V)

2400

19600

14000

9250

5650

2900

Find a suitable **equation** which relates the property value *V* to the time after the wind turbines were installed *t*.

Basically if I can get some help with the equation I should be able to do the rest which is just Predictions from the graph.

Sorry if this is too big or probably in the wrong spot, much help appriciated.

Cheers.
