Understanding Limits and Unbounded Behavior

The video tutorial explores the concept of limits using the functions 1/x^2 and 1/x. It discusses how the limit of 1/x^2 as x approaches zero is unbounded, meaning it does not approach a finite value. The tutorial also examines the limit of 1/x, where approaching zero from the left results in negative infinity and from the right results in positive infinity, leading to the conclusion that the limit does not exist. The video introduces the idea of unbounded limits and sets the stage for future discussions on infinity and limit notations.

What is the main focus of the graph discussed at the beginning of the video?

• y = x^2

• y = 1/x^2

• y = x

• y = 1/x

As x approaches zero from the left for 1/x^2, what happens to the values?

• They remain constant

• They oscillate

• They become smaller and smaller

• They become larger and larger

What happens to the values of 1/x^2 as x approaches zero from the right?

• They become smaller and smaller

• They remain constant

• They become larger and larger

• They oscillate

What term is used to describe a limit that does not approach a finite value?

• Bounded limit

• Unbounded limit

• Finite limit

• Stable limit

What is the behavior of 1/x as x approaches zero from the left?

• It oscillates

• It becomes more negative

• It becomes more positive

• It remains zero

When approaching zero from the right for 1/x, what happens to the values?

• They become more positive

• They become more negative

• They oscillate

• They remain constant

What is the behavior of 1/x as x approaches zero from the right?

• It oscillates

• It becomes more negative

• It becomes more positive

• It remains zero

In the context of limits, what does it mean when values are unbounded in different directions?

• The limit exists

• The limit is finite

• The limit does not exist

• The limit is stable

What is the conclusion about limits when approaching different directions?

• The limit is finite

• The limit is stable

• The limit does not exist

• The limit is oscillating

What is the significance of the direction in which values become unbounded?

• It determines if the limit is stable

• It determines if the limit exists

• It determines if the limit is oscillating

• It determines if the limit is finite
