1. Understanding that a function from one set, called a domain, to another set, called a range, assigns to each element of the domain exactly one element of the range. HSF. IF. A.1
2. Use function notation, evaluate functions for their inputs in their domains, and interpret statements that use function notations in terms of a context. HSF. IF. A.2
3. For a function that models a relationship between two quantities, interpret the features of graphs and tables in terms of the quantities, and sketch graphs showing key features as intercepts, intervals where the function is increasing, decreasing, positive or negative, relative maximums and minimums. HSF. IF. B.4
4. 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. F-IF.B.5
