Assignment 2

Investigating Parabola Graphs

by

Jen Curro


Produce several (5 to 10) graphs of

 

on the same axis using different values for D.

 

Here are what eight graphs look like for different values of d

 

 

 

 

Notice that the term submitted for d is the x value of the vertex.

 

Varying D does not change the slope of the graph. The slope does not change because the coefficient in front of the first term () is not different. A varying slope will occur when this coefficient varies.

 

Varying D does however change the position of the graph by moving it's vertex horizontally across the y=-2 line
