Quadratics

Nota:

• The axis of symmetry of a parabola is the vertical line that divides the parabola into two congruent halves

Nota:

• the point where the parabola crosses its axis of symmetry

1. Nota:

   • The curve formed from all points  (x, y)
   • graphs of quadratic functions

Nota:

• when parabolas open up, the vertex is the lowest point on the graph

Nota:

• when the parabola opens down, the vertex is the highest point on the graph

1. Only vertical parabolas have a Max + Min
