FUNction and RELAtion.

This the a not bad until, it give me another chance to learn about graphing because in my science class right now, I am also going graph so this really helps me. In the begainning of this unit it was confusing because the the teacher explan to us saying a *function is a rule that turns "an in put" into "an out put" * A rule that turns one thing into another *a rule that turns a number into another number. when he tell us to write it down in our dictionary, i just go "Huh" "Eh" "what" "where" when" "how. because iam just going like INPUT? OUTPUT? what on earth are those. Later on when i see more examples and think about it, it really mean that to find out if a graph is a function or not then to check if you can see 2 dots of y-int. and only one of x-int. then the graph is not a function, but if you see one dot in the y-int. 1 dot in x-int then is a function.
