what is the range of this quadratic function?

Explanation:

Step1: Identify vertex

The vertex of the parabola is at (-8, 0). Since the parabola opens upwards (the graph goes up on both sides from the vertex).

Step2: Determine range

The minimum value of the function is the y - value of the vertex. The range is all y - values greater than or equal to the y - value of the vertex.

Answer:

$y\geq0$
