Question

Does the function ƒ(x) = (1∕2) + 25 represent exponential growth, decay, or neither?A) Exponential growth

B) Impossible to determine with the information given.
C) Neither
D) Exponential decay

Answer 1

Explanation:

Answer 2

D) Exponential decay

Explanation:

The correct function is:

`f(x) = 25(1/2)^x`

Required

What type of rate is it

An exponential function is represented as:

`f(x) = ab^x`

If

`b > 0`, then it represents growth

`b < 0`, then it represents decay

By comparison:

`b = 1/2`

`1/2 < 0`

Hence, the rate is exponential decay
