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