A Region A graph of f(x) discloses lots of activity. Two Zeros of f(x), a relative or local minimum, an inflection point and a relative or local maximum. So for x in the interval say (-2.24, -1.98) y is jumping! Can you run the first and second derivative tests to support the graph information? Give it a try please.
Interesting Polynomial Points In: Region B has a zero of this function. Can you find it?
Region C contains a point where the curve goes across it's tangent line.
Region D has a point of f(x) that is way down low. How low?
