Parabolas Because you need them, for physics and stuff

Parabolas  The graph of a quadratic equation  Comprised of several parts  Vertex  Axis of Symmetry  X-interceptS (maybe?)  Y – intercept

Axis of Symmetry  The central line that splits the middle of the parabola  Remember: what is the formula for vertical lines  What kind of slope?

Vertex  The center point of the parabola  The line of symmetry runs through this point  Is either the minimum or maximum point of the parabola

Minimum/Maximum  Parabolas open either upward or downward  If the parabola opens upward, the vertex is the lowest point, known as the minimum.  a>0, aka positive  If the parabola opens downward, the vertex is the highest point, known as the maximum.  a<0, aka negative
