The graph of a polynomial is given. Identify the degree of the polynomial, the turning points, and any x-intercepts. Also estimate any local maxima or minima and any absolute maxima or minima.
What will be an ideal response?
Degree = 3;
Turning points ? (-1.1, 4.1) and (1.8, -8.2);
x-intercepts: x = -2, x = 0, x = 3;
Local maximum ? 4.1;
Local minimum ? -8.2;
Absolute maximum: none;
Absolute minimum: none
