Vertical Line Test and Function Classification

The video tutorial covers the concepts of relations and functions, explaining how to determine if a relation is a function and whether it is one-to-one. It introduces mapping diagrams and the vertical line test as tools to identify functions. The tutorial provides examples and visual aids to help understand these mathematical concepts.

What is the primary goal when classifying relations and functions?

• To determine if they are exponential

• To determine if they are functions

• To determine if they are quadratic

• To determine if they are linear

What is a key characteristic of a function?

• Each output has exactly one input

• Each output has multiple inputs

• Each input has exactly one output

• Each input has multiple outputs

In a set of ordered pairs, what indicates that a relation is not a function?

• All inputs map to the same output

• All outputs map to the same input

• An output maps to multiple inputs

• An input maps to multiple outputs

What defines a one-to-one function?

• No two inputs map to the same output

• All outputs map to the same input

• Multiple inputs map to the same output

• All inputs map to the same output

How can you identify a one-to-one function using outputs?

• Check if any input is repeated

• Check if all inputs are the same

• Check if any output is repeated

• Check if all outputs are the same

What is a mapping diagram used for?

• To visualize exponential functions

• To visualize relations and functions

• To visualize linear functions

• To visualize quadratic functions

In a mapping diagram, what indicates a function?

• Each input maps to multiple outputs

• Each input maps to exactly one output

• Each output maps to exactly one input

• Each output maps to multiple inputs

What does a shared output in a mapping diagram indicate?

• The relation is a function

• The function is not one-to-one

• The relation is not a function

• The function is one-to-one

What is the vertical line test used for?

• To determine if a graph is exponential

• To determine if a graph represents a function

• To determine if a graph is linear

• To determine if a graph is quadratic

What does it mean if a graph passes the vertical line test?

• The graph is quadratic

• The graph is linear

• The graph is a function

• The graph is not a function
