Describing Graphs of Polynomial Functions

Describing Graphs of Polynomial Functions 1.14 - Solution

arrow_back Return to Describing Graphs of Polynomial Functions

We want to estimate the coordinates 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.

As we can see above, the graph has turning points at about and The point corresponds to relative maximum and the point corresponds to relative minimum.

Next, we will estimate the zeros of the function. 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
