Describing Inverses of Functions

Describing Inverses of Functions 1.2 - Solution

arrow_back Return to Describing Inverses of Functions
The first step is to determine the function's inverse. To find the inverse of the function, we will first switch and Now, we will isolate the variable. The result will be the inverse of the given function.
Solve for
Now that we found the inverse of the function, we can determine whether it represents a function. A function is a relation where each input is related to exactly one output. In this case, for each in domain of the inverse, there is only one value of in the range. Therefore, the inverse is a function in its domain. The function is invertible.
