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

Chris wanted to transform the graph of the parent function by horizontally compressing it so that it has a period of units, horizontally translating it units to the right, and vertically translating it 1 unit up. To do so, he graphed the function , as shown. What did he do wrong?

Question illustration
A
He graphed the function incorrectly because he didn’t translate the graph of the parent function 1 unit up.
Option A
B
He graphed the function incorrectly because the period of the transformed function is not units.
Option B
C
He graphed the function correctly, but it was not the right function to graph. He should have graphed .
Option C
D
He graphed the function correctly, but it was not the right function to graph. He should have graphed .
Option D

Which is the graph of the function ?

Question illustration
A
On a coordinate plane, the x axis ranges from negative 2 pi to 2 pi with an interval of pi by 2 units and the y axis ranges from negative 6 to 6 with an interval of 2 units. It shows a curve that oscillates between positive and negative infinity as x approaches multiples of pi. The curve has vertical asymptotes at x equals plus or minus n times pi. The graph increases in every pi interval as x increases. The curve crosses the x axis at (2 pi comma 0), (pi comma 0) and (negative pi comma 0) and (negative 2 pi comma 0).
