Man kann jede quadratische Funktion durch die Gleichung '''f(x) = ax<sup>2</sup> + bx + c''' ausdrücken. Deshalb nennt man diese Form auch die '''Normalform'''.
|}<br/>
 
 
 
Wie dir vielleicht schon aufgefallen ist, ist in der Normalform nicht nur a und c, sondern jetzt auch ein '''b'''.<br/>
Probiere am daneben stehenden Graphen selber aus, was sich an einer Parabel durch '''b''' ändert.

Auch Flugbahnen von Bällen haben die Form einer Parabel.<br/>
Dirk Nowitzki möchte einen Korb werfen. Hilf ihm, indem du durch variieren von '''a''', '''b''' und '''c''' die Flugbahn seines Balles in den Korb lenkst. Dazu muss die Parabel sowohl den Basketball als auch den Korb berühren.
