Eve’s teacher asked her to graph the function by reflecting the graph of the function about the x-axis and translating it vertically. Does it matter in which order Eve does the transformations?

Question illustration
A
Yes, it matters. The graph of the function should be reflected about the x-axis before it is translated 1 unit down.
Option A
B
Yes, it matters. The graph of the function should be reflected about the x-axis before it is translated 1 unit up.
Option B
C
No, it doesn’t matter. Reflecting the graph of the function about the x-axis and translating the graph 1 unit down in either order will produce the correct graph.
Option C
D
No, it doesn’t matter. Reflecting the graph of the function about the x-axis and translating the graph 1 unit up in either order will produce the correct graph.
Option D
