Topic: Range of a function

I'd like to illustrate the range of a function. I have tried to do it drawing the shadow between the graphic and the y-axis but there is a problem with functions of this type: y=1/(x–1). How can I do it?

Re: Range of a function

You are right. Graph seems to have a problem shading under this functions. I will look into how to solve the problem.

For now you can use an inequality as a workaround. If you insert this relation you should get the area you want:

x<1/y+1 xor x<0
