Find a formula for a value of an item that is depreciating over time? What formula is that, I have a college final tomorrow.

How is it deprciating? There are many answers:

p(t)=3*(2)^(-t) will decrease by one-half every unit of time passed with an initial price of 3.

p(t)=3-log(1+t)) will decrease, but will only be an acceptable model for t < 1000

you can make many such functions.

He said on the review sheet that exact sentence, followed by (handout), which he never gave us. WTF.

Sounds like he has a specific function in mind; one that he probably talked about in class.

Maybe on a day i was absent, i doubt that though, he is a new teacher. Which means he trying but he still is getting use to teaching.
