This math topic focuses on determining the minimum or maximum y-value of quadratic functions given their vertex and the direction in which they open (up or down). The problems involve identifying either the minimum or maximum y-values based on the vertex coordinates and the orientation of the parabola. This requires an understanding of the vertex form of quadratic functions and how the vertex relates to the graph's highest or lowest point, depending on whether the parabola opens upwards or downwards. Each question provides multiple choice answers for the students to select from.
