Which relation describes a function? What makes it a function?
A) {(-2,3),(-2,5),(-6,7)} Each member of the range is unique.
B) {(2,3),(3,3),(3,4)} Each member of the domain and range is positive.
C) {(2,3),(3,3),(3,4)} Each member of the domain and range is a real number.
D) {(-2,3),(-3,3),(-4,3)} Each member of the domain is assigned exactly one member of the range.

Answer:I believe the answer is D because it won’t be a function if the x is repeating

Answer:

D) {(-2,3),(-3,3),(-4,3)} Each member of the domain is assigned exactly one member of the range.

Step-by-step explanation:

A mathematical function is the relationship between one magnitude and another, when the value of the first depends on the second. In this way, every mathematical function consists of the relationship between an element of group A and another element of group B, provided that they are uniquely and exclusively linked. Therefore, this function can be expressed in algebraic terms as follows:

[tex]f: A\rightarrow B\\\\a\rightarrow f(a)[/tex]

Hence, given a set A and a set B, a function is the association that occurs when each element of the set A (the domain) is assigned a single element of the set B (range).
