WebSep 26, 2013 · If an algebraic function is one-to-one, or is with a restricted domain, you can find the inverse using these steps. Example: f (x) = (x-2)/ (2x) This function is one-to-one. Step 1: Let y = f (x) y= (x-2)/ (2x) Step 2: solve for x in terms of y y= (x-2)/ (2x) 2xy=x-2 multiply both sides by 2x 2xy-x=-2 subtract x from both sides WebThe inverse is usually shown by putting a little "-1" after the function name, like this: f-1(y) We say "f inverse of y" So, the inverse of f (x) = 2x+3 is written: f-1(y) = (y-3)/2 (I also used y instead of x to show that we are …
