How can you tell if a function has an inverse
WebFor something like this, I would just make sure the function is one-to-one / injective. This is because if a function is injective, then it has an inverse as well. WebTo find the inverse of a function, you can use the following steps: 1. In the original equation, replace f (x) with y: to. 2. Replace every x in the original equation with a y and every y in the original equation with an x. Note: It is much easier to find the inverse of functions that have only one x term. For functions that have more than one ...
