Final answer:
The inverse of the function y = x is y = x. To find the inverse, swap the variables x and y and solve for y.
Step-by-step explanation:
The inverse of the function y = x is the function y = x.
To find the inverse of a function, we swap the variables x and y and solve for y. In this case, we have y = x. Swapping x and y, we get x = y. Therefore, the inverse function is y = x.
For example, if the original function is y = 2x, the inverse function would be x = 2y. The inverse function mirrors the original function across the line y = x.
