Lesson: Relations and Functions Mathematics • Third Year of Preparatory School

Join Nagwa Classes

Attend live Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to identify, represent, and recognize functions from schematic descriptions, arrow diagrams, and graphs.

Students will be able to

define a function,
determine whether a relation is a function from a relation diagram, a table, and a set of ordered pairs,
determine whether a relation is a function from its schematic descriptions or equation,
determine equations that can be defined as functions,
represent functions using diagrams, sets of ordered pairs, equations, and graphs,
define and find a domain, a codomain, and a range of discrete functions (as sets),
find unknowns given that a relation between two sets is a function.
