$\"\"$

The function is $\"\"$ .

Rewrite the function $\"\"$ .

$\"\"$

Now we can write perfect square.

$\"\"$ $\"\"$

Compare the above equation with $\"\"$ , then $\"\"$ .

The vertex of the function is $\"\"$ and axis symmetry is $\"\"$ .

The graph opens up and has the same shape as the graph of $\"\"$ ,

but it translated 4 units right and 2 units up. $\"\"$

Draw a coordinate plane.

Plot the vertex, $\"\"$ .

Draw the graph of $\"\"$ .

Draw the axis of symmetry, $\"\"$ .

$\"garph$ $\"\"$

The graph of the function $\"\"$ is
