The video tutorial explains non-continuous functions, focusing on graph characteristics and undefined points. It introduces jump discontinuity and evaluates limits at specific points, emphasizing the concept of continuity from both sides of a point.

What is the behavior of the function at x = 0?

• It is continuous and equals zero.

• It is a closed circle.

• It equals one.

• It is undefined.

What type of discontinuity is present in the function?

• Removable discontinuity

• Oscillating discontinuity

• Jump discontinuity

• Infinite discontinuity

What is the limit of the function as x approaches 1?

• Undefined

• 2

• 1

• 0

When evaluating limits, what is the significance of approaching from both the left and right?

• It confirms the function's continuity at that point.

• It helps determine if the limit is infinite.

• It identifies the function's maximum value.

• It shows the function's derivative.

What happens to the function value as x approaches 1 from both sides?

• It approaches 0.

• It remains undefined.

• It approaches 1.

• It approaches 2.
