To find the real zeros of the function, set f(x) equal to zero and solve for x.

The polynomial function .

                                  (Set f(x) equal to zero)

                                        (Add to each side)

                                         (Take square root to each side)

So, the real zeros are .

The real zeros are .

The degree of polynomial function " f " has " n " real zeros and the graph of  " f " has, at most " " turning points.

The polynomial function .

The degree of polynomial function is 2.

Since the graph of has  turning point.

The factor , k > 1, yields a repeated zero x = a of multiplicity k.

If k is odd, the graph crosses the x - axis at x = a.

The polynomial function .

The factor form of polynomial function .

The factor , k = 1, Since the multiplicity is odd.

The odd multiplicity and number of turning points 1.

The polynomial function .

The polynomial function graph is
