 Relations pair an element of its domain with an element of its range  The inverse pairs an element of the range with an element of the domain:  Example: (x, y) is the ordered pair of a relation (y, x) is the ordered pair of the inverse

 Find the inverse of the following equations: ◦ Is the inverse a function?

 Consider the following function: ◦ Find the domain (x-values) and range (y-values) of ◦ Find (inverse of ) ◦ Is the inverse a function?
