Observe the graph:

a.

Find the end behavior.

Since end behavior is in opposite direction, hence the leading coefficient is negative.

b.

Degree of the function.

It is odd degree polynomial function.

c.

Find the number of real zeros.

The function touches the -axis at three points.

There are three -intercept and it has three real zero.

End behavior is in opposite direction.

It is odd function.

It has three real zeros.
