WebNot all functions have inverses. A function must be a one-to-one function, meaning that each y-value has a unique x-value paired to it. Basically, the same y-value cannot be used twice. The horizontal line test can determine if a function is one-to-one. Imagine finding the inverse of a function that is not one-to-one. greencoast springs florida https://rhinotelevisionmedia.com
