How to Invert a Function Coffee Mug

Do you have any idea how many times LabKitty gets asked how to invert a function? Answer: so many times that we have said if we are ever in bed with a giant multinational conglomerate having trinket printing capabilites we're gonna do something about it. Students, hobos, strangers on the bus, nightclub floozies, Jehovah's Witnesses - what is it about inverting functions that people find so fascinating? Assuming we don't lead some sort of charmed other-worldly existence (meh, you never know) we can only assume that you, too, are constantly set upon by such folk. Good folk to be sure - real salt-of-the-Earth types - but, still, there's a time when you just want to enjoy your froyo in peace. So we offer these instructions for you to display publicly. Step 1: rotate paper by 90 degree counter-clockwise. Step 2: flip paper over. Bam! There it is: the inverse function. You might have to hold the paper up to the light to see it, but nontheless, you're back to your froyo. LabKitty: looking out for you in ways no one else can or will.
