Below shows v, the dollar valua of a share of a certain stock, as a function of t, the time in weeks since the initial offering of the stock. Find a possible formula for v(t).

t v

0 250.
1 189.46
2 143.59
3 108.82
4 82.47
5 62.50
6 47.37

I got y = 250 (.4347)^x

IS THAT CORRECT?
 
"Correct" is a difficult word. It does not seem to relate to what you were asked to do. Is your formula a good representation of the data? If so, and you can show your rational development, then you have a good answer.

250*0.4347 = 108.675 -- Hmmm...That's not very close 189.46. Perhaps you should rethink it. Too bad you did not share with us your methodology.

Hint:
189.46/250 = 0.75784
 
Wilc, you're guessing as usual.
Look at it as receiving a negative interest rate compounding weekly.
