Question

which graph does not have a minimum?

Explanation:

Step1: Analyze the graph shape

A minimum occurs where a graph changes from decreasing to increasing. Graph II is a parabola opening downward.

Step2: Determine the existence of minimum

For a parabola opening downward, there is a maximum (highest point) but no minimum (lowest point). Graphs I and III have points where they change from decreasing to increasing (local minima).

Answer:

II
