Given a table, equation or written description of a quadratic function, graph that function, and determine and interpret its key features.

### Clarifications

*Clarification 1*: Key features are limited to domain; range; intercepts; intervals where the function is increasing, decreasing, positive or negative; end behavior; vertex; and symmetry.

*Clarification 2*: Instruction includes the use of standard form, factored form and vertex form, and sketching a graph using the zeros and vertex.

*Clarification 3*: Instruction includes representing the domain and range with inequality notation, interval notation or set-builder notation.

*Clarification 4*: Within the Algebra 1 course, notations for domain and range are limited to inequality and set-builder.
