To estimate: The coordinates of each turning points and state whether each corresponds to a
The real zero of the function is
The given function is a 3rd degree polynomial.

Given information:
Graph of a function
Formula used:
The x -intercepts of a function are the points where graph crosses the x -axis.
A local maximum of a function occurs at a turning point such that the point is higher than all neighborhood points.
A local minimum of a function occurs at a turning point such that the point is lower than all neighborhood points.
Calculation:
From the given graph, it is visible that the graph crosses the x -axis approximately at
There are two turning points for the given graph. The least degree of a polynomial function is one more than its turning points, therefore, the given polynomial is a 3rd degree polynomial.
The local maxima occurs at
