Answer:

The answer is


{f}^( - 1) (x) = (x +3 )/(25)

Explanation:


f(x) = 25x - 3

To find the inverse of f(x) , equate f(x) to y

That's

y = f(x)

We have


y = 25x - 3

Next interchange the terms that's x becomes y and y becomes x


x = 25y - 3

Next solve for y

Move 3 to the other side of the equation

That's


25y = x + 3

Divide both sides by 25


(25y)/(25) = (x + 3)/(25)

We have the final answer as


{f}^( - 1) (x) = (x +3 )/(25)

Hope this helps you
