Example Question #23 : How To Find F(X)
Given
Find .
Substituting in place of
above equation one gets the following:
which, after simplification, gives us the correct answer which is
Example Question #24 : How To Find F(X)
Given
and
Find
Example Question #1 : Mean
There exists a function f(x) = 3x + 2 for x = 2, 3, 4, 5, and 6. What is the average value of the function?
14
25
4
20
6
14
First we need to find the values of the function: f(2) = 3 * 2 + 2 = 8, f(3) = 11, f(4) = 14, f(5) = 17, and f(6) = 20. Then we can take the average of the five numbers:
average = (8 + 11 + 14 + 17 + 20) / 5 = 14
