Question

Which function is not an example of exponential decay?



y= 0.5(3)x
y= 2(0.4)x
y= 3(0.2)x
y= 0.2(0.5)x

Answer 1

Exponential decay happens where we have a number less than 1 in the base, or a number less than 2 in the exponent.

Answer 2

Seems like there is only one choice where we don't have a number less than 1 in the base. Which one is it?

Answer 3

c?

Answer 4

Naw.

Answer 5

In the case \(y = 0.5(3)^x\), we have 0.5 as the coefficient; 3 as the base; x as the exponent.

Answer 6

We don't have to do with what x is, because x is a variable. See what the bases are.

Answer 7

dddd

Answer 8

naw. Where we DON'T have an exponential decay.

Answer 9

OHH a ?

Answer 10

Yes.
