Understanding Domain and Range of Continuous Graphs

What does the domain of a continuous graph represent?

• The lowest point on the graph

• The highest point on the graph

• The x-values from left to right

• The range of y-values

How do you represent a closed circle in inequalities?

• Using an equal sign

• Using a bracket

• Using a parenthesis

• Using a less than or greater than sign

In interval notation, what symbol is used to represent infinity?

• A bracket

• A parenthesis

• An equal sign

• A plus sign

When a graph has an arrow, what does it indicate about the domain or range?

• It has a closed circle

• It is limited to a specific range

• It extends indefinitely in one direction

• It has a fixed endpoint

How is a domain with no restrictions typically described?

• As a single point

• As a finite set

• As a closed interval

• As all real numbers

What is the interval notation for a domain that extends from negative infinity to 3 with an open circle at 3?

• (-∞, 3]

• (-∞, 3)

• [3, ∞)

• (3, ∞)

In a graph with a domain from -4 to 4, how would you represent this using inequalities?

• -4 > x > 4

• -4 < x < 4

• x = -4 or x = 4

• -4 ≤ x ≤ 4

What does a closed circle on a graph indicate about the value at that point?

• The value is infinite

• The value is not included

• The value is included

• The value is undefined

How would you describe a range that starts at 10 and goes to positive infinity?

• y ≥ 10

• y ≤ 10

• y > 10

• y < 10

If a graph's range is from 2 to 8 with closed circles, how is this represented in interval notation?

• (2, 8)

• [2, 8]

• (2, 8]

• [2, 8)
