Evaluate the left hand limit at an asymptote algebraically

The video tutorial explains the concept of limits, focusing on approaching numbers from the left on a number line. It uses the example of approaching -4 and discusses the calculation of limits using specific values. The tutorial emphasizes understanding positive and negative outcomes in limits and concludes with the concept of asymptotes and positive infinity.

What does it mean to approach a number from the left on a number line?

• To ignore the number

• To surpass the number

• To get close to the number from smaller values

• To reach the number exactly

When calculating limits, why is it important to consider the sign of the result?

• Because it affects the direction of the limit

• Because it determines the exact value

• Because it changes the number line

• Because it makes the calculation easier

Why is it unnecessary to calculate the exact values when evaluating limits?

• Because the values are irrelevant

• Because the values are always positive

• Because the sign of the result is more important

• Because the exact values are always zero

What happens when you divide a negative number by another negative number?

• The result is undefined

• The result is negative

• The result is positive

• The result is zero

What is an asymptote in the context of limits?

• A point where a function is undefined

• A line that a graph approaches but never touches

• A number that a function reaches

• A value that makes a function zero
