Answer:
The function
is the inverse of the function

Explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x.
So, for the function
swap the variables:
becomes

Now, solve the equation
for y.

For the function
swap the variables:
becomes

Now, solve the equation
for y.

Therefore, the function
is the inverse of the function

Here is the graph of the function and inverse. We can see that the graph of the inverse is a reflection of the actual function about the line y = x. This will always be the case with the graphs of a function and its inverse.
