Lesson: Identifying Functions Mathematics

Start Practising

In this lesson, we will learn how to identify a function from a relation shown by a set of ordered pairs, a relation diagram, an equation, or a graph.

Lesson Plan

Students will be able to

define what is meant by a function,
identify whether a set of ordered pairs defines a function,
identify functions from relation diagrams,
understand how to use the vertical line test to determine whether a relation’s graph represents a function,
understand the conditions for which an equation can be represented in function notation, .
