Answer 1

This is the graph that I got

Answer 2

The graph represents a polynomial of grade 3. Ther curve has two passes at y=0 in the values of x equal to -1 and to -2, a maximum approximately at x = -1.5 and a minimum approximately at x equals to 2.25. In the attached figures are shown the curve in at extended range and in the right, the zoom shows the two zeros, the maximum and the minimum.
