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 … WebInverse Rational Function. A rational function is a function of form f (x) = P (x)/Q (x) where Q (x) ≠ 0. To find the inverse of a rational function, follow the following steps. An example is also given below which can help you to understand the concept better. Step 1: Replace f (x) = y. Step 2: Interchange x and y.
