Example of relation and function?
A function must be well defined. This means that every element in the domain maps to only one element in the range. In more math terms, let a and b be in the domain of f such that a = b. If f is a function, then if a = b, f(a) = f(b). A relation does not need to be well defined. An example of this would be y^2 = 4. y = 2 or -2. An ordered pair that would be part of a relation but not a function would be (x, y^2) vs an ordered pair possible in a function which would be (x^2, y).
Which ordered pair could you remove from the relation (2 1) (1 1) (1 0) (0 1) (1 0) so that it becomes a function?
The right part of the relation needs to be unique - no numbers may be repeated. It's clear that in this case, you would need to remove more than one pair.
What prism would name a ordered pair?
A prism cannot be used to name an ordered pair.
Find the relation ship between confluent hypergeometric function and laguerre polynomials?
OK, it's found. Now, how would you like it presented, and do you want fries with that ?
Why the order of the numbers in an ordered pair is important?
Because otherwise it would not be an "ordered" pair.
