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

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

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.

How exactly do you clear the graph? Since were not typing the equations in the Y= part. If that makes sense.
