rule, table of values and graph
It is a function from the set of x-values to the set of y-values.
Yes.
If you know some values, then you at least have a function of some sort, but you don't know what other values might be. To be a useful function you must be aware that a rule exists to calculate its value for any situation, and preferably know what the rule (equation or whatever) is.
For each rule draw a table with 5 rows and 2 columns. At the top of each table write a caption denoting which rule applies to that particular table. In the top row of each table write the letter "X" in the first column and the letter "Y" in the second column. Now for each table in the first column in rows 2,3,4, and 5 write the values of X that apply to the experiment. Now apply the rule for each value of X for a particular table (particular rule) and write the value of Y (obtained by observation or calculation) in the corresponding column

rule, table of values and graph
A table of values is no use if the domain is infinite.
A function calculates a value based on some other values (or several values), using some rule. The only rule that functions must follow is that the value calculated for the function must be uniquely defined.

dignity, freedoms, rights, equity, rule of law
It is a function from the set of x-values to the set of y-values.

Yes.
When you say it's a "rule of the rich", as in the Golden Rule (he who has the gold, rules)."This plutocracy keeps the poor aware of everything...or not."
