Which of the following could be the equation Which of the following could be the equation of the function below? A coordinate plane. The graph starts and rises to (negative pi comma 1). It starts to fall through (negative 9 pi over 10 comma 0) to (negative 4 pi over 5 comma negative 1). It then rises through (negative 7 pi over 10 comma 0) to (negative 3 pi over 5 comma 1). It then falls through (negative pi over 2 comma 0) to (negative 2 pi over 5 comma negative 1). It then rises through (negative 3 pi over 10 comma 0) to (negative pi over 5 comma 1). It then falls through (negative pi over 10 comma 0) to (0 comma negative 1). It then rises through (pi over 10 comma 0) to (pi over 5 comma 1). It then falls through (3 pi over 10 comma 0) to (2 pi over 5 comma negative 1). It then rises through (pi over 2 comma 0) to (3 pi over 5 comma 1). It then falls through (7 pi over 10 comma 0) to (4 pi over 5 comma negative 1). It then rises through (9 pi over 10 comma 0) to (pi over 5 comma 1). y = negative 2 cosine (4 (x pi)) minus 1 y = 2 cosine (x pi) 1 y = negative 2 cosine (2 (x pi)) minus 1 y = 2 cosine (4 (x pi)) 2of the function below? on a coordinate plane, a curve crosses the y-axis at y = negative 3. it has a maximum at y = 1 and a minimum at y = negative 3. it goes through 1 cycle at pi. y = negative 2 cosine (4 (x pi)) minus 1 y = 2 cosine (x pi) 1 y = negative 2 cosine (2 (x pi)) minus 1 y = 2 cosine (4 (x pi)) 2
