Explanation
Choice D is correct. For the quadratic function , the vertex of the graph is 
, and because the 
term is positive, the vertex is the minimum of the function. Choice D is the only option that meets these conditions.
Choices A, B, and C are incorrect. The vertex of each of these graphs doesn’t correspond to the minimum of the given function.
