Exploring Domain and Range of Continuous Graphs

This video tutorial explains how to identify the domain and range from continuous graphs. It covers the concepts of domain as x-values and range as y-values, and how to determine these from graph points and arrows. The video also distinguishes between continuous and discrete graphs, and provides examples of how to write compound inequalities for domain and range. Additionally, it discusses how to interpret graphs with arrows that indicate direction, emphasizing the importance of understanding graph behavior in terms of left-right and up-down movements.

What type of graphs include line segments, lines, and shapes that are not just points?

• Pie charts

• Bar graphs

• Continuous graphs

• Discrete graphs

What do the X values represent in a graph?

• Domain

• Range

• Width

• Height

If a point on a graph is represented by a closed circle, what does it indicate?

• The value is an estimate

• The value is not included

• The value is included

• The value is unknown

What do arrows on a graph typically indicate?

• The graph has a maximum value

• The graph changes direction

• The graph continues indefinitely

• The graph ends at that point

How do you represent that a graph includes all real numbers for X values?

• X such that X is an element of all real numbers

• X such that X is greater than 0

• X such that X is between two values

• X such that X is less than 0

What is the highest point on a graph called?

• Minimum

• Mode

• Maximum

• Median

In a discrete graph, how are the values listed?

• From largest to smallest

• From smallest to largest

• In alphabetical order

• In random order

What does the range of a graph represent?

• T values

• Z values

• Y values

• X values

If a graph has an open circle, what does it indicate about the value?

• The value is included

• The value is not included

• The value is an estimate

• The value is unknown

In a graph with a ray, what does the arrow indicate?

• The graph changes direction

• The graph ends at that point

• The graph has a maximum value

• The graph continues indefinitely in that direction
