Determine domain and range and if a relation is a function

The video tutorial explains how to determine the domain and range of a set of ordered pairs and assess if the set is a function. It begins by defining ordered pairs and their components, then moves on to explain how to identify the domain using X coordinates and the range using Y coordinates. Finally, it discusses the criteria for determining if the set is a function, emphasizing that each element in the domain must correspond to exactly one element in the range. The tutorial concludes that the given set is a relation, not a function, due to multiple correspondences for a single domain element.

What is the domain of the set of ordered pairs discussed in the video?

• 1, 3, 5, -3, 0

• 1, 3, 5, -3

• 1, 3, 5, 0

• 1, 3, 5, -3, 1

Which of the following values is part of the range identified in the video?

• 5

• 14

• 3

• 1

What must be true for a set of ordered pairs to be considered a function?

• Each element in the domain corresponds to multiple elements in the range.

• Each element in the domain corresponds to exactly one element in the range.

• Each element in the range corresponds to multiple elements in the domain.

• Each element in the range corresponds to exactly one element in the domain.

Why is the set of ordered pairs in the video not a function?

• Because -3 corresponds to 0.

• Because 1 corresponds to both -7 and 2.

• Because 5 corresponds to 14.

• Because 3 corresponds to 8 and 5 corresponds to 14.

Which of the following is NOT a correct statement about the domain and range?

• Domain consists of all X values.

• Range consists of all Y values.

• Domain is also known as output values.

• Range is also known as output values.
