Q

Describe how to create a graph of an of degree polynomial using the linear model.

Décrire comment créer un graphique d’un polynôme de degré en utilisant le modèle linéaire.

A

Cubics have two directions that the wheel of the car is turned while generally following the idea of the slope from the linear equivalent.

Quintics have four phases of the wheel being turned either right or left.

The degree is always one more than the wheel directions.

Les cubiques ont deux directions dans lesquelles la roue de la voiture est tournée, tout en suivant généralement l’idée de la pente de l’équivalent linéaire.

Les quintiques comportent quatre phases de rotation de la roue vers la droite ou vers la gauche.

Le degré est toujours supérieur d’une unité aux directions de la roue.

Q

A polynomial with degree 9 has how many wheel directions?

Un polynôme de degré 9 a combien de directions de roue ?

A

8

Wheel directions are often referred to as turning points, though that term is not clear enough to grasp the meaning, so look for wheel directions and use that number for questions asking for turning points.

8

Les directions des roues sont souvent appelées points d’inflexion, bien que ce terme ne soit pas suffisamment clair pour en saisir le sens. Cherchez donc les directions des roues et utilisez ce chiffre pour les questions portant sur les points d’inflexion.

Q

How do you make the points appear on the graph once you have them in the regression list?

Comment faire apparaître les points sur le graphique une fois qu’ils figurent dans la liste des régressions ?

A

2nd, y= (to access stat plot), enter, highlight on, enter, graph

Zoom, stat

The above will help the zoom display the points you have entered clearly

Make sure your equations in ‘y =’ are deleted so that you can see your points clearly
