Whаt is the equаtiоn оf the grаph shоwn? A purple curve is graphed on a coordinate plane with x labeled −2π, −π, 0, π, and 2π. The graph consists of repeating decreasing branches that fall steeply from very high y-values to very low y-values within each interval. Each branch crosses the x-axis near the midpoint of its interval, including at the origin. The curve approaches vertical lines between these intervals, indicating vertical asymptotes. The repeating pattern continues regularly across the interval from −2π to 2π.
