Answer:

y = -7x+3

Explanation:

We can write the function as

y = (3-x) / 7

To find the inverse of this function we have to do 2 things

a. change x with y and y with x and

b. find the y

a. y = (3-x) / 7, change x with y and y with x

x = (3-y) / 7, multiply both sides by 7

b. 7x = 3-y, subtract 3 from both sides

7x-3 = -y, multiply both sides by -1

-7x+3 = y

The inverse function of

f(x) = (3-x)/7 is
f^(-1) (x) = -7x + 3
