1.7 - 1.8 Practice

Find points of discontinuity (restrictions on the domain).

• A

• B

• C

• D

Answer explanation

The point of discontinuity occurs where the function is undefined or has a break. Choice B identifies such a restriction on the domain, making it the correct answer.

VA and hole?

• A

• B

• C

• D

Answer explanation

The correct answer is A because it directly relates to the concept of VA (voltage amplification) and hole (a charge carrier in semiconductors), making it the most relevant choice in this context.

Domain?

• A

• B

• C

• D

Answer explanation

The correct answer is D because it accurately represents the domain in question, while options A, B, and C do not align with the required criteria. Therefore, D is the best choice.

Write an equation given the asymptotes.

• A

• B

• C

• D

Answer explanation

The correct choice, C, represents the equation that aligns with the given asymptotes. It accurately reflects the behavior of the function near the asymptotic lines, confirming its validity.

What are the asymptotes?

• A

• B

• C

• D

Answer explanation

Asymptotes are lines that a graph approaches but never touches. Choice A correctly identifies the asymptotes of the given function, making it the right answer.

Which is the correct graph?

• A

• B

• C

• D

Answer explanation

Graph B correctly represents the data trends shown in the question, while the other options do not align with the expected patterns or values. Therefore, B is the correct choice.

Which is the correct graph?

• A

• B

• C

• D

Answer explanation

Graph D is the correct choice as it accurately represents the data trends and relationships indicated in the question. The other options do not align with the expected outcomes.

Which is the correct graph?

• A

• B

• C

• D

Answer explanation

Graph A is the correct choice as it accurately represents the data trends and relationships described in the question, while the other options do not align with the expected outcomes.

List the transformations.

• A

• B

• C

• D

Answer explanation

The correct choice is C, which accurately lists the transformations required. Choices A, B, and D do not provide the correct or complete transformations needed for the question.

What is the function of the graph?

• A

• B

• C

• D

Answer explanation

The graph's function is best represented by option D, which accurately describes the relationship or data being illustrated. Options A, B, and C do not align with the graph's purpose.
