To estimate: the coordinates of given turning point, to state whether h=given corresponds to a
Answer to Problem 32E
Least degree of the function is 3.
The local maximum is at about
The local minimum is at about
The real zeros are 2.5.
Explanation of Solution
Given information:
Given graph,
Calculation:
From the graph it is very clear that it has two turning points.
Because it has two points, so least degree of the function is
The coordinate of a turning is a local maximum of the function when the point is higher than all nearby points.
From the graph it is very clear that, the local maximum is at about
The coordinate of a turning is a local minimum of the function when the point is higher than all nearby points.
From the graph it is very clear that, the local minimum is at about
From the graph it is very clear that, it crosses axis at about
Therefore, the real zeros are 2.5.
