Whаt is the equаtiоn оf the grаph shоwn? A coordinate plane is shown with the x-axis labeled from 0 to about 35 and the y-axis labeled from 0 to 15. A red curve begins at approximately (0, 4) on the y-axis. From that point, the curve increases as x increases, rising quickly at first and then more gradually, indicating a decreasing slope. By around x = 35, the y-value is slightly above 10. The graph remains above y = 4 and shows no turning points.
