F−1(f(x)) = f(f−1(x)) =

Given:

To find:

The missing value.

Solution:

We have,

      ...(i)

We know that, if is a function and is its inverse function, then

         ...(ii)

From (i) and (ii), we get

Missing value =

Therefore, the missing value is , i.e., .

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
