The quadratic function is .

The above function compare with .

Rewrite the function

*a* = 3, *b* = 0 and *c* = 0.

The *y*-intercept of the equation is* c* = 0.

The equation of the axis symmetry is .

(Substitute the values *a* = 3 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.
