Intro to Functions and Slope

What is the definition of the Domain of a Relation?

• The Domain is defined as one, and only one, y-value for each x-value.

• The Domain is the Slope of a line.

• The Domain represents all of the x-values within a Relation.

• The Domain represents all of the y-values within a Relation.

What is the definition of the Range of a Relation?

• The Range is defined as one, and only one, y-value for each x-value.

• The Range is the Slope of a line.

• The Range represents all of the x-values within a Relation.

• The Range represents all of the y-values within a Relation.

What is the definition of a Function?

• A Function is defined as a Relation in which for every x-value there is one, and only one, y-value.

• A Function is defined as a Relation in which for every y-value there is one, and only one, x-value.

• A Function represents all of the x-values within a Relation.

• A Function represents all of the y-values within a Relation.
