Question

if (20,14) is an ordered pair of the inverse of f(x) which of the following is an ordered pair of the function f(x)

Answer 1

(14, 20) is the ordered pair of the function f(x)

Solution:

Given that,

(20, 14) is an ordered pair of the inverse of f(x)

We have to find the ordered pair of the function f(x)

In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain

To find the ordered pair of the function f(x),  we swap the variables x and y

(y, x) of inverse of f(x) becomes (x, y) of f(x)

Therefore, (14, 20) is the ordered pair of the function f(x)
