Question

Which function represents exponential decay?

Answer 1

Lets say f(x) is your exponential function
f(x)=a^x
where a can be any positive real number.
In this case depending on the value of a it will be growing or decaying.

Answer 2

What value of a will give decay?

Answer 3

D?

Answer 4

I wont solve your problem just guide you to the solution

Answer 5

I will give you examples
\[f(x)= 2^x\]

Answer 6

In this case a=2, is this a decaying function or a growing?

Answer 7

Pamela16 said she thought D was the answer. But this is not correct. If you sub in increasing numbers for x, like x = 2 then x = 3, the function h(x) also goes up. So D is exponential growth, not decay.
