OG详解-OG5 数学1 Q3

Choice D is correct. They-intercept of a graph is the point where the graph intersects the y-axis. The graph of function f shown intersects the y-axis at the point (0, 8). Therefore, the y-intercept of the graph of f is (0, 8).
Choice A is incorrect. This is the point where the x-axis, not the graph of f, intersects the y-axis. Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors.
