Question

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

Explanation:

Step1: Identify the vertex

The graph is a parabola opening upwards, so its vertex is the minimum point. The vertex is at the origin \((0, 0)\) as seen from the graph (intersecting the \(x\)-axis and \(y\)-axis at \((0,0)\)).

Step2: Determine the minimum value

The \(y\)-coordinate of the vertex gives the minimum value of the function. Since the vertex is \((0, 0)\), the minimum value is \(0\).

Answer:

\(0\)
