Describe a function and its inverse in your own words.

A function is a mathematical relationship between two sets of values, where each input value has a corresponding output value. The inverse of a function is the opposite of the original function, where the output values become the input values and the input values become the output values. For example, if the original function is y = 2x + 1, then the inverse function would be x = (y - 1) / 2.
You might add that a function f(x) and its inverse f^-1 (x) are
a reflection of each other in the line y = x
a reflection of each other in the line y = x
