Question

What function below is the inverse of :

Answer 1

The second option is right, because inverse means opposite. And to get the opposite just flip it and you have your answer.

Answer 2

The given function is:

`y=(7x-1)/(2)\\\\2y=7x-1\\\\2y+1=7 x\\\\x=(2y+1)/(7)\\\\ \text{Replacing x by y and y by x ,to get inverse of the function}\\\\y=(2x+1)/(7)\\\\f^(-1)(x)=(2x+1)/(7)`
