Question Analysis
This question tests the student's understanding of the end behavior of a quadratic function. The key is to identify the leading coefficient and determine the direction in which the parabola extends as approaches positive infinity.

Key Concept Explanation
The end behavior of a quadratic function is determined by the sign of the leading coefficient . If a > 0, the parabola opens upward, and if a < 0, the parabola opens downward. In this case, , so the parabola opens downward.

Step-by-step Solution
1. Identify the leading coefficient in the quadratic function
