Greetings to you, Sir CPhill:

I seeth ye have made changes to thy avatar and address. The byway of 666 hath and leadeth to many remarkable wizards and sorcerers. Yea, it passeth by the castle and mansions of Morgan le Fay, who be one with the greats and who resideth near that byway.

The path be potent and hath may powers. The bolder of Sisyphus hath rolled on this path in times of times, and ye may even findeth the Roman ZERO for which ye be searching.

"D" is correct........to find an inverse graph (if you have a good mind for pictures)....imagine the original graph being put in a mirror....then......rotate this image 90 degrees clockwise (i.e., a quarter turn clockwise).......that will be the inverse graph !!!

I am confused?

The original graph is missing is it not?

What is D the inverse of?

The inverse is the reflection of the original function in the line y=x   (It is not a rotation)

I am all confused now!

Maybe you description is correct too Chris.  I am just having trouble getting my head around it.

Your description of an inverse function was kinda weird Chris :)))

I used to get that a lot when I was tutoring this topic....but try it for yourself......a "mirror image" rotated 90 degrees clockwise will produce the inverse......(if there is an inverse)

Yea well a reflection in the line y=x works to and it makes a lot more sense.

But you can do it you way - nothing like variety  LOL

The forum Ghost has been at it again!   Should we have an exorcism?

Probably not - our ghost says some really nice things sometimes.

I wonder what it is called when you exorcise a Troll ?   We could maybe do with one of those.

Maybe Chiurgeon Tud may know how it is done.  I wonder if he is in Camelot at the present.

I think that no one has seen him for more than a moon.

CPhill have you seen Chiurgeon Morgan Tud of late?

Nope....he must have gone on a quest for that Roman zero !!!  (or maybe he's off to help Sisyphus !!!)

Here be a possible reason why the image ye seek come not forthwith.

There be many incantations in the crystal sphere that call forth spirits and graven images made by spirits.

In the beginning, the surf who made the post calleth the images from many domains and the images came forth. Now, it be that one of the domains hath vanished. Some of these domains be temporary and appeareth for a little while then vanishes away.

After the domain vanishes, if wizard’s assistant in the crystal sphere calleth for a graven image the wizard findeth that it does not exist, and never will again in this place, then to saveth time, the incantation be removed, for there now be no reason to use an incantation to call forth a graven image from a domain that exists not.

The graven images for choices of answers be in domains that still exist, and the incantation to call them still exists, so, they display when called.

In Her Majesty’s service,

Good day Chuirgeon Tud.

It be a bonny eve.  Thank thee for appearing so promptly.

We of Camelot hath missed thy presence.  Can thee linger in the passages of this magical castle for a while. Thy weary bones need resting from all the great travel thee has had in recent times.  Yes stay.  Tend our ill and provide us with the healing powers of thy great humour.

Hath thee seen my sister-in-law Morgan Le Faye.  She be a very powerful Sorceress.

Perhaps we of Camelot can call upon her to help control our unruly Troll.  Of her I did not think.

Perhaps Sir CPhill can take the path and search out the boulder of Sisyphus and Lady Morgan at one time.

What say you Sir CPhill?
