If a function's graph passes the Horizontal Line Test (i.e. no two points have the same y-value), then the function's inverse will also be a function.

The inverse function is a function obtained by reversing the given function. The domain and range of the given function are changed as the range and domain of the inverse function. Let us …

The inverse function of $f$ is simply a rule that undoes $f$'s rule (in the same way that addition and subtraction or multiplication and division are inverse operations.) Consequently, the range …

One example is a linear function with a non-zero slope, like f (x) = 2 x + 3. Its inverse (y = x − 3 2 ) is also a function. Any one-to-one and onto function will have an inverse that is also a function.

For the most part, we disregard these, and deal only with functions whose inverses are also functions. If the inverse of a function is also a function, then the inverse relation must pass a …

For you: see if you can do the steps to create that inverse! Inverses of Common Functions. It has been easy so far, because we know the inverse of Multiply is Divide, and the inverse of Add is …

Example 1: Find the Inverse of a Function (1 of 2) The function is one-to-one. It has a domain and range consisting of all real numbers. Find its inverse function. Note that f(x) can be replaced …

In this section, we define an inverse function formally and state the necessary conditions for an inverse function to exist. We examine how to find an inverse function and study the …

Here are some examples of functions and their inverses, showing some key points: The same function! Notice from the graphs above: The inverse graphs are the original graphs reflected …
