Answer 1

Answer:

1/7-21x is right answer of this question

Answer 2

Concept:

The Inverse of a function:

A function which can reverse into another function.

Given:

We are given a function:

F(x) = 1/3 - 1/21 x

Find:

We need to find the inverse of it.

Solution:

We have:

F(x) = 1/3 - 1/21 x

We can also write it as:

y = 1/3 - 1/21 x

1 / 21 x = 1 / 3 - y

x = 7 - 21 y

which can also be written as:

f⁻ (y) = 7 - 21 y

f⁻ (x) = 7 - 21 x.

Therefore, we get the inverse of the function as f⁻ (x) = 7 - 21 x.
