Performance Objectives: Within the context of this lesson, students will be asked to:
• Define a ‘function’.
• Compare a ‘relation’ with a ‘function’.
• Contrast a ‘relation’ with a ‘function’.
• Identify whether a set of ordered pairs is a ‘function’ or just a ‘relation’.
• Justify why a set of ordered pairs is OR is not a function.
Common Core Standards: 8th Grade
CCSS.Math.Content.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.
CCSS.Math.Content.8.F.A.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
• What is a relation?
• What is a function?
• Can you compare and contrast a relation and a function?
• Can you describe a real life example of a function?
• Can you determine whether a relation is a function?
• Can you justify your decision when determining whether a relation is a function?
