Evalauate the limit of a piecewise function with a hole

The video tutorial covers the basics of quadratic equations, focusing on graph behavior and identifying holes. It explains how to evaluate function values and approach limits using direct substitution. The instructor uses a specific quadratic equation to demonstrate these concepts, emphasizing the importance of understanding graph behavior and the limitations of certain values.

What does the equation X^2 - 3X + 1 represent in terms of its graph?

Explain the significance of the hole in the graph at X = 1.

How do you find the value of the function as X approaches 1?

Discuss the behavior of the graph as X approaches the hole at X = 1.

What is the result of direct substitution in the equation when X = 1?
