$\"\"$

The function is $\"\"$

(a) Type of curve and symmetry:

The equation is in the form of $\"\"$ , where $\"\"$ and $\"\"$ .

The function represents leminiscate.

Then, Replace $\"\"$ is $\"\"$

Substitute $\"\"$ in the function.

$\"\"$

The function is symmetric.

$\"\"$

(b)Maximum $\"\"$ -value and zeros.

The equation $\"\"$ is undefined But the domain of $\"\"$

The graph point of interval is $\"\"$

Therefore the function has maximum point.

Then $\"\"$ value is $\"\"$ when $\"\"$ .

(c) Graph the polar equation.

Graph the polar equation $\"\"$ .

Draw a table considering points in the interval $\"\"$ .

Graph :

Draw polar coordinate plane.

Plot the points obtained in the table.

Graph the polar equation $\"\"$ .
