The quadratic function is $\"\"$ .

The above function compare with $\"\"$ .

Rewrite the function $\"\"$

a = $\"\"$ , b = 4 and c = $\"\"$ .

The y-intercept of the equation is c = $\"\"$ .

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

$\"\"$ (Substitute the values a = $\"\"$ and b = 4)

$\"\"$ (Simplify)

The x-coordinate of the vertex is $\"\"$ .

The equation of the axis symmetry is $\"\"$ and x-coordinate of the vertex is $\"\"$ . $\"\"$

Make a table of values that includes the vertex.
