Colin McAllister replied to VASUDEVA KH's discussion How to introduce concept of function? in the group Introducing Math Concepts
"The metaphor of a machine is appropriate for explaining a function. When a function is computerised, as in a graphing calculator, that is exactly how the function is implemented, as a machine, with floating point numbers representing real numbers.…"

"The following example of a circle drawn in a Cartesian coordinate system illustrates some of the points being discussed. The equation of a circle of radius r is not a function: This can be rearranged to express x as a square root: and y as a…"

"I also use the concept of a machine; I made a quickie starter mathcast to show you what I mean: http://www.screencast.com/t/XLyggaJAXaxn As I said in video, I don't actually introduce functions, but rather review them to kids who never really…"

Dylan Faullin replied to VASUDEVA KH's discussion How to introduce concept of function? in the group Introducing Math Concepts
"To clarify my comments, I do not literally repeat the definition 50 times consecutively, as in a mantra. But at each relevant moment, I repeat the definition, perhaps stating it slightly different, perhaps encouraging the class to 'fill in the…"

Dylan Faullin replied to VASUDEVA KH's discussion How to introduce concept of function? in the group Introducing Math Concepts
"y is a function of x when: for each allowed value of x, there is only one possible answer for y. Repeat that about 50 times and I find that students have a pretty decent understanding. I say this when looking at tables of values to determine if…"
