How to find the limit of a constant function

The video tutorial explains a function represented by a constant line at y = -1. It discusses the behavior of the function as X approaches different values, particularly focusing on X approaching 2 from the right. The tutorial emphasizes that the function's value remains consistently negative, regardless of the direction from which X approaches. This concept is reinforced by considering other values like 7 and 8, highlighting the function's unchanging nature.

What does a function represented by a constant value, such as -1, look like on a graph?

• A parabolic curve

• A diagonal line

• A vertical line

• A horizontal line

As x approaches positive 2 from the right, what happens to the value of the function?

• It increases

• It decreases

• It oscillates

• It remains constant

What is the value of the function as x approaches any number from the right?

• It becomes undefined

• It becomes positive

• It remains negative

• It becomes zero

Does the direction from which x approaches a value affect the function's constant value?

• Yes, it changes the value

• No, it remains the same

• No, it becomes undefined

• Yes, it becomes zero

What concept is highlighted by the function's value remaining constant regardless of the approach direction?

• Limits

• Differentiation

• Continuity

• Integration
