Study Notes

Functions and Relations

A Function assigns exactly one output for each input, ensuring consistency in the relationship.
An Input is the numerical value or quantity you provide to obtain a specific output in a function.
An Output is the resulting numerical value or quantity derived from the provided input.

Ordered Pairs

An Ordered Pair consists of two numbers that represent a relationship between two elements and is formatted as (x, y), where order matters.

Relations

A Relation encompasses all possible ordered pairs that represent the association between inputs and outputs, forming a set of pairs.

Visual Representation

Mapping serves as a visual tool for illustrating a relation, using arrows to connect inputs to their corresponding outputs, highlighting the function's nature.

Analyzing Graphs

The Vertical Line Test is a method used to determine if a graph represents a function by observing if any vertical line intersects the graph at more than one point.
