Question

look at this graph: graph of a parabola what is the minimum value of this function?

Explanation:

Step1: Identify the vertex

The graph is a parabola opening upwards, so the vertex is the minimum point.

Step2: Read the y - coordinate of the vertex

From the graph, the vertex is at (0, -10), so the y - coordinate (which is the minimum value of the function) is -10.

Answer:

-10
