Which of the following is the graph of y = cosine (2 (x + pi))?
A coordinate plane. The graph starts and rises through (negative 24 pi comma 0) to (negative 21 pi comma 1). It starts to fall through (negative 18 pi comma 0) to (negative 15 pi comma negative 1). It then rises through (negative 12 pi comma 0) to (negative 9 pi comma 1). It then falls through (negative 6 pi comma 0) to (negative 3 pi comma negative 1). It then rises through (0 comma 0) to (3 pi comma 1). It then falls through (6 pi comma 0) to (9 pi comma negative 1). It then rises though (12 pi comma 0) to (15 pi comma 1). It then falls through (18 pi comma 0) to (21 pi comma negative 1). It then rises through (24 pi comma 0).
A coordinate plane. The graph starts and rises through (negative 2 pi comma 0) to (negative 7 pi over 4 comma 1). It starts to fall through (negative 3 pi over 2 comma 0) to (negative 5 pi over 4 comma negative 1). It then rises through (negative pi comma 0) to (negative 3 pi over 4 comma 1). It then falls through (negative pi over 2 comma 0) to (negative pi over 4 comma negative 1). It then rises through (0 comma 0) to (pi over 4 comma 1). It then falls through (pi over 2 comma 0) to (3 pi over 4 comma negative 1). It then rises though (pi comma 0) to (5 pi over 4 comma 1). It then falls through (3 pi over 2 comma 0) to (7 pi over 4 comma negative 1). It then rises through (2 pi comma 0).
A coordinate plane. The graph starts and rises through (negative 8 pi comma 0) to (negative 6 pi comma 1). It starts to fall through (negative 4 pi comma 0) to (negative 2 pi comma negative 1). It then rises through (0 comma 0) to (2 pi comma 1). It then falls through (4 pi comma 0) to (6 pi comma negative 1). It then rises through (8 pi comma 0).
A coordinate plane. The graph starts and rises through (negative 8 pi comma 0) to (negative 7 pi comma 1). It starts to fall through (negative 6 pi comma 0) to (negative 5 pi comma negative 1). It then rises through (negative 4 pi comma 0) to (negative 3 pi comma 1). It then falls through (negative 2 pi comma 0) to (negative pi comma negative 1). It then rises through (0 comma 0) to (pi comma 1). It then falls through (2 pi comma 0) to (3 pi comma negative 1). It then rises though (4 pi comma 0) to (5 pi comma 1). It then falls through (6 pi comma 0) to (7 pi comma negative 1). It then rises through (8 pi comma 0).
