5. Let X = {a, b, c) and Y = {d, e, f, g}.
Does the following arrow diagram determine a function from X to Y? Explain. (6 Pts)
b. What are the domain, and codomain

Best ResponseYou've already chosen the best response.0two x values can have the same why but not vice versa i think

Best ResponseYou've already chosen the best response.2yes another way to say it is a function can be manytoone but not onetomany

Best ResponseYou've already chosen the best response.0yes @welshfella but is that one a function?

Best ResponseYou've already chosen the best response.0Do the elements on X and Y need to be the same number?

Best ResponseYou've already chosen the best response.2what is different with this relation is that you have values of y not linked with a value of x. To be honest i don't know for sure.

Best ResponseYou've already chosen the best response.0the codomain, is all of the output values, the set contains all of the 'graphed' points that are mapped by the rule X>Y, Plus possibly more.

Best ResponseYou've already chosen the best response.0Like say for example, if you have the function f(x) = x^2 The Domain is all real numbers, the range of that is just numbers greater than zero...

Best ResponseYou've already chosen the best response.0the codomain though is all real numbers,

Best ResponseYou've already chosen the best response.0x >x^2, both can be any real number, but the actual image of the graph does not have negative values, so the co domain includes the negative values, the range is just positive values

Best ResponseYou've already chosen the best response.0so the whole set Y is the codomain

Best ResponseYou've already chosen the best response.0it does not matter that some elements are not used?

Best ResponseYou've already chosen the best response.0right, the codomain possibly includes values that aren't graphed by the function

Best ResponseYou've already chosen the best response.0f(x) = x^2 Domain  All Reals Range  y >=0 codomain  all reals

Best ResponseYou've already chosen the best response.0X > X^2 you can choose any number for X, domain You can choose any number for X^2, codomain the results area always positive, Range or the actual graph
