The quadratic function is .

The above function compare with .

Rewrite the function

*a* = 2 , *b* = and *c* = .

The *y*-intercept of the equation is* c* = .

The equation of the axis symmetry is .

(Substitute the values *a* = 2 and *b* = )

(Simplify)

The *x*-coordinate of the vertex is .

The equation of the axis symmetry is and *x*-coordinate of the vertex is 1.5.

Make a table of values that includes the vertex.
