The quadratic function is
.
The above function compare with
.
Rewrite the function 
a = 1 , b = 0 and c =
.
The y-intercept of the equation is c =
.
The equation of the axis symmetry is
.
(Substitute the values a = 1 and b = 0)
(Simplify)
The x-coordinate of the vertex is 
The equation of the axis symmetry is
and x-coordinate of the vertex is 0.
Make a table of values that includes the vertex.
