Evaluate the limit to infinity and negative infinity from a graph

The video tutorial explains the concept of limits in calculus, focusing on how functions behave as X approaches infinity or negative infinity. It discusses the difference between the actual value of a function at a point and the value it approaches, using limit notation. The tutorial also covers how to evaluate function values and the importance of considering both left and right approaches when determining limits.

What happens to the y-value of a function as x approaches infinity?

• The y-value approaches negative infinity.

• The y-value remains constant.

• The y-value approaches infinity.

• The y-value approaches zero.

As x approaches negative infinity, what is the behavior of the y-value?

• The y-value approaches negative infinity.

• The y-value remains constant.

• The y-value approaches infinity.

• The y-value approaches zero.

What is the value of the function at x = 3 if there is a hole at that point?

• The value is infinity.

• The value is where the dot is.

• The value is undefined.

• The value is 0.

How is the limit of a function at a point determined?

• By the value of the function at that point.

• By the values the function approaches from the left and right.

• By the average of the function values.

• By the maximum value of the function.

What is the difference between evaluating a function and finding its limit?

• Evaluating a function gives the actual value, while the limit is about approaching values.

• Evaluating a function considers only the left side.

• Finding a limit considers only the right side.

• Finding a limit gives the actual value, while evaluating is about approaching values.
