128. identify which functions are exponential. for the functions that are exponential, use the properties of exponents to identify the percent rate of change, and classify the functions as indicating exponential growth or decay.
b.g(x) = 3/4x

g(x) is an exponential decay function.

Step-by-step explanation:

Given : Function

To find : Identify the exponential function and classify the functions as indicating exponential growth or decay ?

Solution :

An exponential function is a nonlinear function of the form , where a ≠ 0, b ≠ 1, and b > 0.

1) When a > 0 and b > 1, the function is an exponential growth function.

2) When a > 0 and 0 < b < 1, the function is an exponential decay function.

On comparing with general function,

The given function is an exponential function.

Where, a=1 and

Here,

i.e. 0<0.75<1 means function is a decay function.

We have the solution:

Since there are three negative numbers being multiplied the product is always negative...

So we have the final answer as -152

Hope this helps
