# Q1 W7 Oct 12-Oct 16 Algebra 1

Teacher Stephanie Durrance Algebra 1 Honors 7th/8th 7 Unit 3 - Introduction to Functions
Standard(s) Taught

Standards Taught:

MAFS. 912.F-IF.1.1: Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y=f(x).

MAFS.912.F-IF.1.2: Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.

MAFS. 912.F-IF.2.6: Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.

MAFS. 912.F-IF.2.4: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship

Learning Targets and Learning Criteria

• define vocabulary (relation, domain and range).
• determine if the correspondence in a graph, table, mapping diagrams or set of ordered pairs represent a function.
• create examples of what is and what is not a function using different representations, including graphs, tables, symbols, and contexts.
