Given any function, f, the inverse of the function, f -1, is a relation that is formed by interchanging each (x, y) of f to a (y, x) of f -1.

Let f be defined as the set of values given by x-values-2047 y-values Let f -1 be defined as the set of values given by x-values y-values-2047

xy Function 1 Function 2 xy y = x

Let To find the inverse, switch x and y, Solve for y: So the inverse of is
