a.)f^-1(x)=x/x+1
b.)f^-1(x)=1/x-1
c.)f^-1(x)=x-1/x+1
d.)f^-1(x)=x/x-1

 The correct option is

(B)

Step-by-step explanation:  We are given to select the correct expression that is the inverse of the following function :

Let y denotes f(x). Then,

Substituting this value in equation (i), we get

Thus, the required inverse of the given function is

Option (B) is CORRECT.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
