What are the steps to find the inverse of a function equation? For example, what is the inverse of f(x) = 2x -7? 4/10/2014 | Crystal from Philadelphia, PA | 2 Answers | 0 Votes Mark favorite Subscribe Comment
f(X ) = 2X -7 Change f(x ) to Y Y = 2X -7 Solve for X in terms of Y: X = (Y + 7 ) /2 Change X to f^{-1 }( X) and Y for X f^{-1} (x ) = 1/2 X +7/2 4/11/2014 | Parviz F. Comment
Set up the equation as y=2x-7 Solve for 'x' Switch 'x' and 'y'. This is your inverse. 4/10/2014 | Stephen W. Comment
