Answer:
C, y ≤ 2
Explanation:
The definition of range is the set of all y-values that a function passes through.
To find the range of a parabola that opens down, find the highest point, or vertex. The range will be y ≤ the y-coordinate of that point.
Since the highest point is (0, 2), the range is y ≤ 2. This is because the parabola will open towards all y-values under 2.
