F(x)=4x+1 over 3 , solve for f ^-1 (3)

Step-by-step explanation:

To find f-¹(3) we must first find f-¹(x)

To find f-¹(x) equate f(x) to y

That's

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

We have

Next make y the subject

Cross multiply

We have

3x = 4y + 1

4y = 3x - 1

Divide both sides by 4

We have

So we have

To find f-¹(3) substitute the value of x that's 3 into f-¹(x)

We have

We have the final answer as
