Overview

In this video lesson, students work with graphs and tables that represent functions. They learn the conventions of graphing the independent variable (input) on the horizontal axis and the dependent variable (output) on the vertical axis and that each coordinate point represents an input-output pair of the function. By matching contexts and graphs and reading information about functions from graphs and tables, students become familiar with the different representations and draw connections between them.

Determine whether a relation is a function, defining a function as a rule that assigns to each input (independent value) exactly one output (dependent value), and given a graph, table, mapping, or set of ordered pairs.

UP:MA19.8.13

Vocabulary

  • Relation
  • Function
  • Input
  • Output

Knowledge

Students know:
  • how to interpret a graph, table, mapping, and ordered pairs.

Skills

Students are able to:
  • give an accurate definition of a function.
  • Analyze graphs, tables, mappings, and sets of ordered pairs to determine if a relation is a function.

Understanding

Students understand that:
  • Functions assign every input one output, but they may see outputs repeat.
