$\"\"$

The function is $\"\"$ .

Rewrite the function in vertex form.

$\"\"$ (Add and subtract $\"\"$ from RHS side)

$\"\"$ (Sum of the square: $\"\"$ )

$\"\"$ (Simplify)

Step 1:

The vertex form is $\"\"$ .

The vertex at $\"\"$ and $\"\"$ .

The axis of symmetry is $\"\"$ .

The graph is narrower than the graph of $\"\"$ .

Step 2:

Plot the additional points to complete the graph.

Graph the function is $\"\"$ .

$\"\"$

Observe the graph:

Plot the additional points are shown.

$\"\"$

Graph of the function is $\"\"$ .
