Week 11: October 19-23

Topic 3-1: “Understand Relations & Functions”

• Standard :8.F.A.1:  Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

• Objective

1. Identify whether a relation is a function

2. Interpret a function

• Essential Understanding

1. A relation is a set of ordered pairs.  A function is a relation in which each input, or x-value, has exactly one output, or y-value.  Arrow diagrams and tables can be used to determine whether a relation is a function.

• Essential Question: When is a relation a function?

Topic 3-2: "Connect Representations of Functions”

• Standard :8.F.A.1:  Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

• Objective

1. Identify functions in different representations:  equations, tables, and graphs

• Essential Understanding

1. Different representations, such as equations, tables, and graphs, can represent a function.  The graph of a linear function is a straight line;  the graph on a nonlinear function is not a straight line.

• Essential Question: What are different representations of a function?

Topic 3-3: “Compare Linear and Nonlinear Functions”

• Standard 

  1. 8.F.A.2:  Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

  2. 8.F.A.3:  Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

• Objective

1. Compare properties of linear functions in different representations

2. Compare properties of linear and nonlinear functions in different representations

• Essential Understanding

1. Two functions presented in different representations can be compared by looking at their properties:  initial value and constant rate of change.

• Essential Question: How can you compare two functions?
