l or press 9.

The initial CONICS screen allows you to choose from various conic functions, including

rectangular, polar or parametric form. You may use the BN to select the equation of the

function in accordance with the type of graph you want to draw. Once you have chosen the conic

function you would like to graph, enter the coefcients of the function and then press DRAW u.

1. To view the graph of the conic: y = 2x

-5x -3, select the y = AX

formula menu.

In the Conics modes, when you press y (G-Solv), although you are still graphing a parabola

like in the graphing section, notice how the vocabulary and options have changed to be conic

specic.

2. For example, you can now examine the line of symmetry for this parabola as the equation

of that line will be displayed.

You can continue to analyze different areas of this graph and the line of symmetry will still

be displayed.
