This may seem crazy to some, but if you've tried to find a particular clipart because you had a great idea for presenting a difficult math concept (like composite functions), you will understand the TURDUCKEN.
turkey = t(x)
duck = d(x)
chicken = c(x)
There are three different images, each in color and blackline - 6 images in all. Use the images to represent the composition of functions; showing how one function is consumed first and the output from the first function becomes the input of the next.
The original idea was not mine, it was a request from another math-creator... I just responded to the challenge.
This resource is the result.
