The function is a downward-opening parabola. Let’s break down the end behavior in detail:
End Behavior Explanation:
1.As :
As you move left along the x-axis toward negative infinity, the parabola decreases from its highest point (the vertex).
Consequently, the y-values also decrease and approach negative infinity.
This means that as x goes to negative infinity, y tends toward .
2.As :
Similarly, as you move right along the x-axis toward positive infinity, the y-values continue to decrease from the vertex.
Thus, as x increases, y also heads toward negative infinity.
Therefore, as x approaches positive infinity, y again approaches
