Understanding Limits from Graphs

The video tutorial explores the concept of limits using graphical representations of functions f(x) and g(x). It examines the limits of f(x) as x approaches 6, 4, and 2, highlighting different scenarios where limits exist or do not exist. The tutorial also analyzes the limits of g(x) as x approaches 5, 7, and 1, emphasizing the importance of approaching the same value from both sides for a limit to exist. The video provides a comprehensive understanding of limits through visual examples.

What is the significance of a limit existing at a point where the function is not defined?

• It indicates a removable discontinuity

• It shows the function is undefined everywhere

• It means the function is continuous

• It implies the function is differentiable
