Understanding Limits of Composite Functions

The video tutorial explains how to evaluate the limit of a composite function using graphs. It covers several examples, including limits as X approaches negative three, negative one, two, and three from the left. The tutorial emphasizes understanding the direction from which a function approaches a limit and translating this understanding between the inner and outer functions in a composite function. Key concepts include approaching limits from different sides and ensuring the correct interpretation of graph values.

What is the limit of f(g(x)) as X approaches negative three?

• 3

• 4

• 2

• 1

When evaluating the limit of a composite function, why is it important to know if G of X approaches from the left or right?

• It affects the final value of the limit.

• It determines the speed of approach.

• It is not important.

• It changes the function being evaluated.

In the context of limits, what does approaching a value from 'above' mean?

• Approaching from lower X values.

• Approaching from higher X values.

• Approaching from lower Y values.

• Approaching from higher Y values.

As X approaches negative one, what is the Y value that G approaches?

• 5

• 2

• 3

• 4

How does the direction of approach affect the limit of a composite function?

• It determines the final limit value.

• It has no effect.

• It alters the function's range.

• It changes the function's domain.

Why do we need to consider both left and right side limits when X approaches 2?

• Because the function is undefined.

• Because the X values are the same.

• Because the Y values differ on each side.

• Because the graph is symmetrical.

What is the significance of the vertical asymptote in the context of limits?

• It marks the end of the graph.

• It is irrelevant to limits.

• It indicates a point of discontinuity.

• It shows where the function is constant.

What is the result when the left and right side limits are different?

• The limit is zero.

• The limit exists.

• The limit is infinite.

• The limit does not exist.

What happens to the limit of f(g(x)) as X approaches 3 from the left?

• It approaches 0.

• It approaches 1.

• It approaches 4.

• It does not exist.

Why is it crucial to determine if G approaches a value from below or above?

• It affects the graph's shape.

• It changes the function's slope.

• It influences the limit's existence.

• It is not crucial.
