The function f(x) = 15(0.965)" models the percentage of surface sunlight, f(x), that reaches a depth of x feet beneath the surface of the ocean. The figure shows the graph of this function. Use the function to determine at what depth, to the nearest foot, there is 1% of surface sunlight. How is this shown on the graph of f? Intensity 20 40 60 80 Depth . . . At what depth is there only 1% of surface sunlight? feet (Do not round until the final answer. Then round to the nearest whole number as needed.) What point on the graph represents this? (Type an ordered pair. Round to the nearest whole number as needed.)
