WebInverse Function. For any one-to-one function f ( x) = y, a function f − 1 ( x) is an inverse function of f if f − 1 ( y) = x. This can also be written as f − 1 ( f ( x)) = x for all x in the domain of f. It also follows that f ( f − 1 ( x)) = x for all x in the domain of f … WebOct 6, 2024 · Find the inverse of the function defined by f(x) = 3 2x − 5. Solution. Before beginning this process, you should verify that the function is one-to-one. In this case, we have a linear function where m ≠ 0 and thus it is one-to-one. Step 1: Replace the function notation f(x) with y. f(x) = 3 2x − 5 y = 3 2x − 5.
