The graph shown gives the height above the water y, in meters, of the diver x seconds after diving from the platform. What is the best interpretation of the x-intercept of the graph?
","rationale_html":"Choice B is correct. It’s given that the graph shows the height above the water y, in meters, of a diver x seconds after diving from a platform. The x-intercept of a graph is the point at which the graph intersects the x-axis, or when the value of y = = is 0. The graph shown intersects the x-axis between x 1 and x 2. In other words, the diver is 0 meters above the water, or hits the water, between 1 and 2 seconds after diving from the platform. Of the given choices, only choice B includes an interpretation where the diver hits the water between 1 and 2 seconds. Therefore, the best interpretation of the x-intercept of the graph is the 1.6 diver hits the water at seconds. Choice A is incorrect and may result from conceptual errors. Choice C is incorrect. This is the best interpretation of the maximum value, not the x-intercept, of the graph. Choice D is incorrect and may result from conceptual errors.
