Master Determining the Domain and Range from a set of points

The video tutorial explains how to determine the domain and range of a set of points. It covers the basics of identifying domain and range using coordinate points, emphasizing the importance of understanding X and Y values. The tutorial also discusses the concept of functions and non-functions, highlighting that a function must have unique mappings from inputs to outputs. Through examples, the video demonstrates how to use set notation to list domain and range values, and it concludes with a final example to reinforce the concepts.

What is the domain in the context of coordinate points?

• The set of all Y values

• The set of all X values

• The set of all Z values

• The set of all input and output values

How is the range defined when identifying it from a set of points?

• The set of all Z values

• The set of all input values

• The set of all X values

• The set of all Y values

Which of the following is true about the range in a function?

• It must be the same as the domain

• It is always larger than the domain

• It cannot have any repeated values

• It can have multiple identical values

What condition must be met for a set of points to represent a function?

• Each input can map to multiple outputs

• Each output must map to a unique input

• Each input must map to a unique output

• Each output must map to multiple inputs

What happens if a domain has the same value mapping to different outputs?

• It is not considered a function

• It is still considered a function

• It becomes a set

• It becomes a range
