Determine domain and range and if a relation is a function

The video tutorial explains how to determine the domain and range from a set of ordered pairs and assess whether the set represents a function. It begins by defining ordered pairs and their components, then moves on to identifying the domain and range. Finally, it explains how to determine if the set is a function by checking if each domain element corresponds to exactly one range element.

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

• 1, 3, 5, -3

• 1, 3, 5, -3, 1

• 1, 3, 5, 0

• 1, 3, 5, -3, 0

Which of the following is part of the range in the video example?

• 5

• 1

• 14

• 3

Which of the following statements is true about the range in the video example?

• The range includes the number 3.

• The range includes the number 14.

• The range includes the number 5.

• The range includes the number 1.

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

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

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

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

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

In the video, why is the set of ordered pairs not considered a function?

• Because -3 corresponds to 0 and 2.

• Because 5 corresponds to 14 and 0.

• Because 1 corresponds to -7 and 2.

• Because 3 corresponds to 8 and 5.
