What is the equation of the graph below? On a coordinate plane, a curve crosses the y-axis at y = 1. It has a maximum of 1 and a minimum of negative 1. It goes through 1 cycle at 5 pi. y = cosine (StartFraction x Over 0.4 EndFraction) y = cos(5x) y = cos(0.4x) y = cosine (StartFraction x Over 5 EndFraction)
