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.
