\

Observe the graph:

\

a.

\

Find the relative maxima and minima occurs at $\"\"$ -coordinate.

\

The graph turns at $\"\"$ and $\"\"$ .

\

The value of the function is greater than the surrounding points at $\"\"$ .

\

Thus graph has the relative maxima at $\"\"$ -coordinate is $\"\"$ .

\

The value of the function is less than the surrounding points at $\"\"$ and $\"\"$ .

\

The graph has the relative minima at $\"\"$ and $\"\"$ .

\

\

b.

\

Find the real zeros.

\

The graph crosses the $\"\"$ –axis at $\"\"$ and $\"\"$ .

\

Thus, the zeroes of the function are $\"\"$ and $\"\"$ .

\

c.

\

Find the degree of the function.

\

The graph of a polynomial of degree $\"\"$ has at most $\"\"$ turning points.

\

That is if the graph of the polynomial has $\"\"$ turning points, then its degree is at least $\"\"$ .

\

The graph has $\"\"$ turning points.

\

Degree of the polynomial should be at least $\"\"$ .

\

d.

\

Find the domain and range.

\

The minimum value of the function is $\"\"$ .

\

So, the range of the function is $\"\"$ .

\

The domain of a polynomial is all real numbers.

\

$\"\"$

\

a.

\

The graph represents the relative maxima at $\"\"$ -coordinate is $\"\"$ .

\

The graph reprsents the relative minima are $\"\"$ and $\"\"$ .

\

b.

\

The zeroes of the function are $\"\"$ and $\"\"$ .

\

c.

\

The degree of the polynomial $\"\"$ .

\

d.

\

The domain of a polynomial is all real numbers and range is $\"\"$ .
