Is there a way to set up your calculator so it will shade in the solution part of a graph. For example: $\displaystyle y>x^2+2x-8\quad y<\frac{1}{x}-2$

You will need to tell us what type of calculator you are using, otherwise nobody will be able to help you.

You find the command Shade with the keys:

2ND*PRGM = Draw

#7 Shade(

The parameters of this command are:

Shade(lowerfunction, upperfunction, left border, right border, pattern [2 = horizontal lines], resolution [3 = every third pixel is drawn])

I've attached a screenshot of the graphs, the settings of the window, the shade command and the effect of this command on the drawing. - Feb 16th 2008, 01:31 PMOzzMan
How exactly do you clear the graph? Since were not typing the equations in the Y= part. If that makes sense.

Use ClrGraph
