Geometry

Question Analysis  

The main focus is to determine the parabola’s orientation by analyzing the positions of the focus and directrix.  

Key Concept Explanation  

Vertical Parabola: Focus and directrix are aligned vertically (focus is above/below the horizontal directrix).  

If the focus is below the directrix, the parabola opens downwards.  

If the focus is above the directrix, the parabola opens upwards.  

Horizontal Parabola: Focus and directrix are aligned horizontally (focus is left/right of the vertical directrix).  

Step-by-Step Solution  

1. Analyze coordinates:  

Focus: (y-coordinate = ).  

Directrix: (horizontal line, y-coordinate = ).  

2. Compare positions:  

The focus lies below the directrix
