# Andregradsfunksjon – eksempel

> Se et eksempel på hvordan en andregradsfunksjon analyseres.

## GRUNNLEGGENDE BEGREPER

Denne leksjonen bruker et konkret eksempel på en andregradsfunksjon. Du lærer å finne viktige egenskaper fra formelen.

## METODE OG BRUK

Vi undersøker nullpunkter, toppunkt og graf og kontrollerer sammenhengen mellom dem. Hvert trinn forklares.

## OPPSUMMERING

Et samlet eksempel viser hvordan algebra og graf henger sammen.
