Understanding Functions and Relations

What is the main question being addressed in the video?

• How to graph equations

• How to solve algebraic equations

• Whether a set of ordered pairs is a function

• The history of mathematics

In a mapping diagram, what does the x-variable represent?

• The range

• The dependent variable

• The output

• The domain

What is a key feature of a function in terms of mapping?

• Each x-value can map to multiple y-values

• Each x-value maps to exactly one y-value

• Each y-value maps to exactly one x-value

• Each y-value maps to multiple x-values

What happens if an x-value maps to more than one y-value?

• It is still considered a function

• It is considered a quadratic function

• It becomes a linear function

• It is considered a relation, not a function
