2. 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.

3. Let f be defined as the set of values given by x-values-2047 y-values04-510 Let f -1 be defined as the set of values given by x-values04-510 y-values-2047

4. xy 13 07 4-5 7-14 Function 1 Function 2 xy 13-2 70 -54 -147 y = x

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