Answer:
Step-by-step explanation:
As we saw before, h represents the x-coordinate of the vertex in the equation y = (x-h)²+k.
Since the parabola is graphed in the xy-plane **above**, this means the parabola opens upwards. With an upwards facing parabola, the vertex is the lowest point on the curve.
Therefore, h can be any value that places the vertex on the x-axis, **but it cannot be positive**.
Out of the options provided, only -2, -5, and -9 satisfy this condition. So, h can be -9, -5, or -2.
