Exploring Relations, Domain, Range, and Interval Notation

Which of the following is NOT a way to represent a relation?

• Ordered pairs

• Table

• Graph

• Equation

In a relation, what are the typical input and output values called?

• A-values and B-values

• X-values and Y-values

• Y-values and Z-values

• X-values and Z-values

What is the domain of a relation?

• The set of all values

• The set of ordered pairs

• The set of input values

• The set of output values

How is a discrete relation characterized?

• By a continuous set of points

• By a set of individual points that are not connected

• By a set of connected lines

• By a set of curves

For the discrete relation with points (-1, 1), (-1, 4), (0, 6), and (4, 8), what is the range?

• [1, 4, 6, 8]

• [-1, 0, 4]

• [0, 1, 4, 6]

• [1, 4, 6, 8, 10]

What is the domain of the discrete relation with points (-3, 2), (0, -1), (3, 3), and (3, -4)?

• [-3, 0, 3]

• [2, -1, 3, -4]

• [-3, 0, 3, 3]

• [-3, 0, 2, 3]

For a continuous relation, how is the domain typically expressed?

• As a table

• As an inequality

• As a set of ordered pairs

• As a list of values

What is the domain of a continuous relation that starts at x = -3 and ends at x = 3?

• [-3, 3]

• (-3, 3)

• [-3, 3)

• (3, -3]

In interval notation, what does a parenthesis ( ) indicate?

• The value is included

• The value is excluded

• The interval is infinite

• The interval is finite

How would you write the interval from -4 to infinity in interval notation?

• (-4, ∞)

• [-4, ∞)

• [-4, ∞]

• (-4, ∞]
