Whаt is the equаtiоn оf the grаph shоwn? A coordinate plane with labeled x- and y-axes is shown. A red curve decreases from left to right with an exponential decay shape. On the left side of the graph, the curve is high above y = 4 and slopes downward steeply. It crosses the y-axis near (0, 1) and continues decreasing. As x increases, the curve flattens and approaches the x-axis, indicating a horizontal asymptote at y = 0.
