Answer:

(4) f(x) = 1250(0.8)^x is the answer

Explanation:

It can be seen that the original price you paid was $1250

After 1 year it was 1000

2 years is 800

3 years is 640

So obviously it's losing value.

But how much value?

We can find how much percentage they are losing by doing this:

1250 x 1.2 or .8 since these are you answers

1250 x 1.2 = 1500, from this we can determine that this answer is WRONG!

The value is going down, and not going up so therefore

It must be

1250 x .8 because when those are multiplied together

You get 1000!

Then 1000 x .8 = 800

800 x .8 = 640!

So we can determine that (4) Is the correct answer.

Hope this helped!
