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

Answer:

The given function is:

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