WebFinding the Inverse of a Function. This video outlines the procedure and do two complete examples of finding the inverse of a function. Examples: If f (x) = √ (x + 4) - 3, find f -1 (x) If f (x) = (5x - 3)/ (2x + 1), find f -1 (x) Show Step-by-step Solutions. Inverse Functions Part 1. This video demonstrates how to find an inverse of a ... WebAn inverse function essentially undoes the effects of the original function. If f(x) says to multiply by 2 and then add 1, then the inverse f(x) will say to subtract 1 and then divide by 2. If you want to think about this graphically, f(x) and its inverse function will be reflections across the line y = x. WebThe inverse of a function can be found for simple linear functions by using function machines. We can do this by finding the inverse operation for each stage in the function machine. It is important to have a strong understanding of inverse operations, for example the inverse of add 3 is subtract 3 and the inverse of square is square root.
