What is the equation of the graph below? A coordinate plane. The graph starts and rises to (negative 8 pi comma 1). It starts to fall through (negative 7 pi comma 0) to (negative 6 pi comma negative 1). It then rises through (negative 5 pi comma 0) to (negative 4 pi comma 1). It then falls through (negative 3 pi comma 0) to (negative 2 pi comma negative 1). It then rises through (negative pi comma 0) to (0 comma 1). It then falls through (pi comma 0) to (2 pi comma negative 1). It then rises though (3 pi comma 0) to (4 pi comma 1). It then falls through (5 pi comma 0) to (6 pi comma negative 1). It then rises through (7 pi comma 0) to (8 pi comma 1). y equal to sine ( StartFraction x over 3 EndFraction) y = sin(3x) y = sin(0.3x) y equal to sine (StartFraction 2x over 3 EndFraction)
