Question

Given the exponential function A(x) = P(1 + r)x, what value for r will make the function a decay function?

Answer 1

any value of r such that 0 < 1+r < 1 will work. That is,

-1 < r < 0

In other words, r is negative, but not by much. That is, (1+r) is a positive fraction, so as x increases, the value of A(x) gets smaller and smaller

Answer 2

ITS SO OBVIOS ITS -2.1 BECAUSE THE MATHEMATICAL GANJA EQUATION HELPS. THE BEST ANSWER IS OBV THAT BC 3248.,123

Answer 3

I just took the test. The answer is -2.1

Answer 4

There is no -2.1
The options are:
r= 2.1
r= -0.1
r= 0
r= 0.1

Answer 5

r=-2.1
