**Evidence Statement Text:**
Relate the domain of a function to a graph and, where applicable, to the quantitative
relationship it describes, limiting to quadratic functions. 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 this function.★
