Answer:
[tex]C\text{ : II only}[/tex]
Explanation:
Here, we want to know the kind of extrema the function has
The function represents a quadratic equation and thus, the graph would be quadratic.
The graph of the function would open upwards since the value of a is positive
Hence in this case, we would have a global minimum at the tail end of the graph
Thus, the kind of extrema possessed by the function would be an absolite minimum
