Exploring Domain and Range in Interval Notation

What is the main difference between interval notation and inequality notation?

• Interval notation uses numbers, while inequality notation uses letters.

• Interval notation uses arrows, while inequality notation uses dots.

• Interval notation uses only brackets, while inequality notation uses only parentheses.

• Interval notation uses brackets and parentheses, while inequality notation uses inequality signs.

In interval notation, what symbol is used to indicate a value that is included in the interval?

• Brackets

• Dots

• Arrows

• Parentheses

For the first example, what is the domain in interval notation?

• [-1, 7]

• (-1, 7)

• [-1, 7)

• (-1, 7]

For the first example, what is the range in interval notation?

• [-4, 8]

• (-4, 8)

• (-4, 8]

• [-4, 8)

In the second example, what does the arrow indicate about the range?

• It extends to positive infinity.

• It starts from a known value.

• It ends at a known value.

• It extends to negative infinity.

For the third example, what is the domain in interval notation?

• (-∞, ∞)

• (-∞, 8]

• (-∞, 8)

• [-∞, ∞]

For the fourth example, what is the range in interval notation?

• (-∞, 2]

• [8, 2]

• (-∞, ∞)

• [8, 2]

In the fifth example, what is the domain in interval notation?

• (-4, 7]

• (-4, 7)

• [-4, 7]

• [-4, 7)

In the sixth example, what does the open circle indicate about the domain?

• The value is included.

• The value is unknown.

• The value is infinite.

• The value is excluded.

For the sixth example, what is the range in interval notation?

• [-7, 3)

• (-7, 3)

• [-7, 3]

• (-7, 3]
