Evaluate the limits from a discontinuos function

The video tutorial covers evaluating function values at specific points on a graph, focusing on identifying closed and open dots to determine these values. It then introduces the concept of limits, explaining how to evaluate them as a graph approaches from the left and right. The tutorial further explores left and right hand limits, discussing their existence and behavior on a graph.

What is the significance of closed and open dots on a graph in relation to function values?

What is the value of the function f at negative 2?

Explain the concept of limits as the graph approaches from the left and right.

What happens to the limit as x approaches 3 from the left and right?

How do you determine if a limit exists or is undefined?
