Which function represents exponential decay? f(x) =1/2(3/2)^x f(x) =1/2(-3/2)^x f(x) = 4(-2/3)^x f(x) = 4(2/3)^x

are u sure
OpenStudy (kittiwitti1):
Please don't give direct answers! :( The exponential growth/decay function is modeled by \(y=Ce^{kt}\), and the value of the rate, variable \(k\), would be negative if you have a decay function.
OpenStudy (kittiwitti1):
Well, it would be that, but I have no idea which one of yours would fit that bill... sorry. Perhaps some more experienced and knowledgeable tutors like @Directrix or @agent0smith can help? (sorry for summoning you so much agent0 haha)
OpenStudy (agent0smith):
It's decay if the base (with the exponent attached) is a number between 0 and 1.
