Wait, don't tell me -- your teachers must have started early on telling you that spelling doesn't count. I guess they were afraid of bruising your fragile little self-esteem. I have no such compulsion. Proper spelling is essential for effective communication. It is can't not "cant". It is instructions not "instrustions". It is function not "funtion"
In a relation defined by a set of ordered pairs, the first element of each ordered pair is the input or domain value. The second element of each ordered pair is the output or range value (sometimes called the codomain). A relation is a function if for each unique value in the domain, there is exactly one (no more, no less) value assigned in the range. If any given domain value has more than one range value, the relation is NOT a function.
