$\"\"$

\

The function $\"\"$ .

\

Change $\"image\"$ to $\"image\"$ .

\

$\"\"$ .

\

The function is half an ellipse.

\

Convert the above equation in standard form of ellipse.

\

$\"\"$ .

\

Squaring on both sides.

\

$\"\"$

\

Compare it to standard form of vertical ellipse $\"\"$ (Center at origin).

\

Where $\"\"$ .

\

$\"\"$ is length of semi major axis and $\"\"$ is semi minor axis.

\

$\"\"$ .

\

In this case major axis length is 6 units and minor axis length is 2 units.

\

\

Graph:

\

Draw the coordinate plane.

\

The function is $\"\"$ .

\

So negative $\"\"$ values are possible.

\

Sketch the curve in third and fourth quadrants only.

\

\

Observe the graph: The $\"image\"$ -intercepts are $\"\"$ , $\"\"$ and $\"\"$ intercept is $\"\"$ .

\

The $\"image\"$ -intercepts are $\"\"$ , $\"\"$ and $\"\"$ intercept is $\"\"$ .
