Question

y=0.75(1.05)t Determine whether the function represents a exponential growth or decay.Identify the percent rate of change

Answer 1

it's growth and by 5%

Answer 2

The function ff(x) = 0.75(1.05)ˣ is an example of an exponential growth function.

The percent rate of change is 5%

What type of function is the equation

From the question, we have the following parameters that can be used in our computation:

f(x) = 0.75(1.05)ˣ

The function ff(x) = 0.75(1.05)ˣ is an example of an exponential growth function.

In exponential growth functions, the base (in this case, 1.05) is greater than 1, and as x increases, the function increases

Also, we have the percent rate of change to be

Rate = 1.05 - 1

Rate = 0.05

So, we have

Rate = 5%

Hence, the percent rate of change is 5%
