$\"\"$

\

A polynomial function $\"\"$ of degree $\"\"$ has at most $\"\"$ distinct real zeros and at most $\"\"$ tuning points.

\

$\"\"$

\

The function is $\"\"$ .

\

The degree of the function is $\"\"$ .

\

Since the degree of the function is $\"\"$ ( $\"\"$ ), the function $\"\"$ has at most $\"\"$ ( $\"\"$ ) distinct real zeros and at most $\"\"$ ( $\"\"$ ) turning points.

\

Find the real zeros by equating $\"\"$ to zero.

\

Solve the equation $\"\"$ by using factoring.

\

$\"\"$

\

Apply zero product property.

\

$\"\"$

\

Thus, real zeros of the function $\"\"$ are $\"\"$ , and $\"\"$ .

\

\

The number of possible real zeros are $\"\"$ .

\

Turning points are $\"\"$ .

\

Real zeros are $\"\"$ , and $\"\"$ .
