How do you find inverse of a function
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 … WebKey Steps in Finding the Inverse of a Linear Function Replace f\left ( x \right) f (x) by y y. Switch the roles of x x and y y, in other words, interchange x x and y y in the equation. Solve for y y in terms of x x. Replace y y by {f^ { - 1}}\left ( x …
