Question

G(x)=3x^2-12x+8 maximum or minimum

Answer 1

Minimum

Step-by-step explanation:

This is what the graph looks like. As you can see, there is no point lower than y=-4. That means the graph has a minimum rather than a maximum.

Here's a shortcut! If the coefficient of x² is positive, the graph has a minimum point. If the coefficient is negative, the graph has a maximum point.
