Answer: C
Step-by-step explanation:
Since y = 0 at x=3pi/2, we know that this is a cosine graph.
So to determine if its -cos or cosine, we can test the pt (0, 1).
Since cos(0)=1 whereas -cos(0)=-1, the answer is y=cos(x).
Answer:
2.
Step-by-step explanation:
Rotating a figure about the midpoint of its diagonal, the figure will coincide with its pre-image two times: at 180° and at 360°.
This is different than rotating about the origin; for a rotation about the origin, a 180° rotation does not always coincide with the pre-image.
hope that answers ur question :))))
