If h(x) is the inverse of f(x), what is the value of h(f(

To answer the question above, make use of one of the definitions of the inverse functions. If h(x) and f(x) are inverses of each other, then applying the operation, h(f(x)) will give back the value of the initial value. Therefore, the answer is x. 

Step-by-step explanation:

Given that h(x) is inverse of f(x0)

As per definition of inverse functions we find that always

f*f inverse = f inverse * f = I = identity function x

Hence here also since h is given to inverse of f we will get composition of functions h and f giving answer as x.

I need an answer for a different question

Step-by-step explanation:

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 9(1.04)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function? (4 points)

Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)

Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?
