Gegeben ist die Funktion f(x) = m·x + t mit m,t \in \mathbb{R} .

Aufgabe 1

Zunächst ist t=0 und die Funktion lautet f(x) = m·x. Verändere den Paramter m beliebig.


Welche Beobachtung machst du? Was passiert bei einem negativen m? Für was steht m in der Funktionsgleichung?


Aufgabe 2

Nun ist m=1 und die Funktion lautet f(x)=x+t. Verändere den Parameter t beliebig.

Welche Beobachtung machst du? Welchen Schnittpunkt des Graphen kann man mithilfe von t direkt in der Funktion selbst ablesen?


Aufgabe 3

Abschließend sind sowohl m und t variabel. Verändere beide Parameter beliebig. Bestätigen sich deine Vermutungen aus Aufgabe 1 und 2?
