Explanation
Choice A is correct. The x-coordinate of any y-intercept of a graph is . Substituting for in the given equation yields . Since any nonzero number raised to the power is , this gives , or . The y-intercept of the graph is, therefore, the point .
Choice B is incorrect and may result from conceptual or calculation errors.
Choice C is incorrect and may result from conceptual or calculation errors.
Choice D is incorrect and may result from conceptual or calculation errors.
