The video tutorial explores the graph of y = g(x) and examines the existence of limits as x approaches specific values. It begins with an introduction to the problem and then analyzes the right-hand and left-hand limits as x approaches 6, concluding that the limit does not exist due to unbounded behavior. The video also discusses the definition and continuity of the function at x=6, highlighting the presence of a vertical asymptote. The tutorial then shifts focus to x=3, analyzing the limits from both sides and determining the function's definition and continuity at this point.

What is the main focus of the first statement discussed in the video?

• The existence of limits as x approaches 6 from both sides.

• The behavior of g as x approaches 3.

• The continuity of g at x = 6.

• The definition of g at x = 6.

What conclusion is reached about the right-hand limit as x approaches 6?

• It is undefined.

• It does not exist.

• It approaches infinity.

• It exists and approaches a specific value.

What is the conclusion about the left-hand limit as x approaches 6?

• It is zero.

• It is equal to the right-hand limit.

• It does not exist.

• It exists and approaches a specific value.

Why does the overall limit as x approaches 6 not exist?

• Because the right-hand limit does not exist.

• Because the left-hand limit does not exist.

• Because both limits exist but are not equal.

• Because g is not defined at x = 6.

What is required for a function to be continuous at a point?

• All of the above.

• The value of the function must equal the limit at that point.

• The limit must exist at that point.

• The function must be defined at that point.

What type of discontinuity is present at x = 3?

• Infinite discontinuity.

• Removable discontinuity.

• Oscillating discontinuity.

• Jump discontinuity.

What is the value of the right-hand limit as x approaches 3?

• It approaches 2.

• It approaches -2.

• It does not exist.

• It is infinite.

What is the value of the left-hand limit as x approaches 3?

• It is infinite.

• It approaches 2.

• It approaches -2.

Is g continuous at x = 3?

• No, because the function is not defined there.

• Yes, because the function is defined there.

• No, because the limit does not exist there.

• Yes, because both one-sided limits exist.
