Question

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

Answer 1

Answer:

D) Exponential decay

Step-by-step 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
