The video tutorial explains how to understand graph discontinuities, focusing on when limits do not exist due to jump discontinuities or asymptotes. It then describes the characteristics of absolute value graphs, noting their continuity and lack of discontinuities. Finally, the tutorial demonstrates calculating limits using direct substitution, emphasizing the simplicity of plugging in values to find the limit.

What is a situation where a limit does not exist?

• When the graph is a straight line

• When the graph is a parabola

• When there is a jump discontinuity

• When the graph is continuous

What shape is the absolute value graph typically described as?

• V-shaped

• U-shaped

• L-shaped

• S-shaped

How is the absolute value graph described in terms of continuity?

• It has asymptotes

• It is continuous

• It has holes

• It has jump discontinuities

What method is used to find the value of a function as X approaches a specific point?

• Indirect substitution

• Numerical approximation

• Graphical analysis

• Direct substitution

What is the result of the limit of F of X as X approaches 0 in the given example?

• Zero

• Negative three

• Three

• Undefined
