A derivative is simply a rate of change. Whether you're modeling the movement of a particle or a supply/demand model, this is a key instrument of Calculus.

The above graph represents the function \(y=g(x).\) Judging the graph as well as you can by eye, what can we say about the derivatives of \(g(x)\) at \(x=-2,0,2?\)
