standard_description: Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes.  For example, if the function h(n) gives the number of person-hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.
problem_activity: Below is a set of coordinate points. Graph these points, connect the points into a linear function, and then graph the inverse of this function.
$${(-2,-4)}$$
$${(1,-2.5)}$$
$${(2,-2)}$$
