Answer:A
The graph above shows y = 2x. Which of the following graphs represents y = |2x|?
A. B. C. D.
Explanation: A Try plugging in some values for x and see if the graphs include that point. If x = 0, then y = 0, so (0, 0) should be a point on the graph. Unfortunately this doesn't eliminate anything. If x = 1, then y = 2, so (1, 2) should be a point on the graph. Eliminate (B), (C), and (D).
