can someone help fast?? 1.) How do you know whether a relation is a function? A) By determining if each value from one set maps to another set such that each element of the domain pairs with exactly one element of the range B) By determining if each value from one set maps to another set such that exactly one element of the domain pairs with exactly two elements of the range C) By determining if each value from one set maps to another set such that exactly one element of the domain pairs with exactly one element of the range D) by determining if each value from one set maps to another set such that each element of the domain pairs with exactly two elements of the range 2.) a domain consists of the value 1,2,3 and 2. a rage consists of the values 5,10,15, and 20. the 1 in the domain corresponds to the 5 in the range, the first 2 in the domain corresponds to the 10 in the range, the 3 in the domain corresponds to the 15 in the range, and the second 2 in the domain corresponds to the 20 in the range. does this relation represent a function? explain. A) it does represents a function. the domain value of 2 corresponds to two values within the range. B) it does represent a function. each value in the domain corresponds to exactly one value in the range. C) it does not represent a function. each value in the domain corresponds to exactly one value in the range. D) it does not represent a function. The domain value of 2 corresponds to two values within the range. 3.) juan has blood type a, lilly has blood type ab, and aaron has blood type o. is this relation a function? explain. A) this relation is not a function. each name in the domain corresponds to exactly two elements in the range of blood types. B) this relation is not a function. each name in the domain corresponds to exactly one element in the range of blood type. C) this relation is a function. each name in the domain corresponds to exactly one element in the range of blood type. D) this relation is a function. each name in the domain corresponds to exactly two elements in the range of blood types. 4.) determine if the set of points (-1.3), (2,5), (3,8), and (4,5) is a function. explain. A) the set of points is a function because each value in the domain corresponds to exactly one value in the range. B) the set of points is not a function because the range consists of the value 5 two times. C) the set of points is not a function because each value in the domain corresponds to exactly one value in the range. D) the set of points is a function is because the range consists of the value 5 two times 5.)isa and benny are both in mrs. johnsons class, patrick is in mr jimenezs class, and jose is in mrs. trues class. is this relation a function? explain. A) this relation is a function because both isa and benny are in mrs johnsons class B) this relation is a function because each student is in exactly one teachers class C) this relation is not a function because both isa and benny are in mrs johnsons class D) this relation is not a function because each student is in exactly one teachers class.
