Begrepp

Ändpunkt

En ändpunkt är en punkt där något börjar eller slutar. Exempelvis kan funktioner, kurvor och intervall på tallinjer ha ändpunkter.

Ändpunkter på kurva och funktion

Om en ändpunkt ingår i en kurva, som t.ex. på intervallet brukar den ritas som en ifylld punkt. Om ändpunkten inte ingår, t.ex. på samma intervall, ritas den oifylld eller vit.

En tallinje med intervallet 1 till 5
