A student is given a quadratic equation in vertex form he determines the vertex and axis of symmetry and then sketches the parabola so that it is symmetrical about the axis of symmetry is this sufficient explain A the vertex and axis of symmetry are not sufficient without intercept and additional sample points falling on the parabola ,there are infinitely many parabola that can be drawn.
B the vertex and axis of symmetry are sufficient as long as the parabolas vertex is located, only one parabola can possibly be graphed
C the vertex and axis of symmetry are not sufficient without the x intercept it is impossible to sketch the graph of a parabola accurately.
D the vertex and axis of symmetry are sufficient as long as the parabola is drawn symmetrically about its axis of symmetry only one parabola can possibly be graphed
