Identifying Functions from Graphs

Why is the function blitz considered a quick way to raise your grade on the GED?

• It focuses on easy-to-understand concepts.

• It covers a lot of material quickly.

• It provides a lot of practice problems.

• It is a fun and engaging way to learn.

What is the main problem being addressed in this video?

• How to draw a graph.

• How to determine if a graph represents a function.

• How to calculate the slope of a line.

• How to solve algebraic equations.

What shape is the graph mentioned in the video?

• A circle

• A straight line

• A hyperbola

• A parabola

What test is used to determine if a graph is a function?

• Horizontal line test

• Slope test

• Vertical line test

• Intersection test

What happens if a vertical line intersects a graph at more than one point?

• The graph does not represent a function.

• The graph is a straight line.

• The graph represents a function.

• The graph is a circle.

In the example, what is the x-value where the vertical line intersects the graph at two points?

• Negative five

• Negative four

• Zero

• Positive four

What does it mean when an x-value is paired with two different y-values?

• The graph is a circle.

• The graph is a straight line.

• The graph is not a function.

• The graph is a function.

What is the 'cheating' analogy used for in the video?

• To show how to solve equations.

• To illustrate x-values paired with multiple y-values.

• To describe the vertical line test.

• To explain how to draw a graph.

What is the conclusion about the graph in the video?

• It is a circle.

• It does not represent a function.

• It represents a function.

• It is a straight line.

What is the key takeaway from the vertical line test?

• A graph is not a function if it is a circle.

• A graph is a function if a vertical line intersects it at multiple points.

• A graph is not a function if a vertical line intersects it at multiple points.

• A graph is a function if it is a straight line.
