Question

Are these transformations right and would there be any others?

Answer 1

Answer: A and D

Step-by-step explanation:

You are correct with the first answer: reflection across the x-axis

You are WRONG with the second answer: It is inside the absolute value so it is horizontal (not vertical).  It is a stretch by a factor of $\frac{1}{3}$, which I am assuming is the same as a compression by a factor of 3. The correct answer is: horizontal compression by a factor of 3.
