Question

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

Answer 1

Please help please

Answer 2

ill help

Answer 3

idk how to do this kind of stuff

Answer 4

its the last one

Answer 5

D

Answer 6

are u sure

Answer 7

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.

Answer 8

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)

Answer 9

It's decay if the base (with the exponent attached) is a number between 0 and 1.
