Question

If f(x) is represented in the table below, which table represents f^-1(x)

Answer 1

Answer:

Option D

Step-by-step explanation:

we know that

If (x,y) is a solution of f(x)

then

(y,x) is a solution of f^-1(x)

In this problem

The ordered pairs in the table that represent f(x) are

(-2,11),(-1,8),(0,5),(1,2),(2,-1)

therefore

The ordered pairs that represent f^-1(x) are

(11,-2),(8,-1),(5,0),(2,1),(-1,2)

The table that represents f^-1(x) in the attached figure
