We want to estimate the coordinate of every turning point. A turning point is either a relative maximum or minimum of the function. Let's look at the given graph to see where the turning points are.
The graph has one relative maximum point and one relative minimum point.
|coordinate of Relative Maximum Point||coordinate of Relative Minimum Point|
We want to estimate the zeros of the polynomial. A zero is the coordinate of the point at which the graph intercepts the axis. Let's consider the given graph.
The zeros occur at approximately and
