Function Identification and Graph Analysis

The video tutorial explains how to determine if a relation is a function using four methods: mapping, tables, graphs, and equations. It covers the concept of domain and range, the vertical line test for graphs, and how to manipulate equations to isolate variables. The tutorial provides examples and highlights key indicators of functions, such as unique mappings from inputs to outputs.

What is the primary focus of the video tutorial?

• Determining if a relation is a function

• Solving complex equations

• Graphing linear equations

• Understanding calculus concepts

Which of the following is NOT a common way to express relations?

• Mapping

• Graphs

• Tables

• Calculus

In a mapping, what do the ovals represent?

• Inputs and outputs

• Equations and solutions

• Functions and relations

• Graphs and tables

What indicates that a mapping is not a function?

• The mapping is circular

• An input maps to more than one output

• There are no outputs

• All inputs map to the same output

What is the domain in a mapping?

• The set of input values

• The set of output values

• The range of the function

• The graph of the function

What is the range in a mapping?

• The domain of the function

• The set of output values

• The graph of the function

• The set of input values

In a mapping, if every input maps to exactly one output, what can be concluded?

• It is a graph

• It is a relation

• It is not a function

• It is a function
