Question

This mapping shows a functional relationship. A mapping diagram shows a relation, using arrows, between domain and range for the following ordered pairs: (2, 4), (negative 3, 0), (negative 1, negative 1), (4, 3). When f(x)=4, what is the value of x? 0 2 3 4

Answer 1

Answer:

$2$

Step-by-step explanation:

Hello!

1) Firstly, let's enlist all the coordinate, (x,y) points to visualize it better.:

$(2,4)\\(3,0)\\(-1,-1)\\(4,3)$

2) Check the pair of sets for this function below. The Domain Set, on the left. The Range set, on the right. This Diagram shows a one to one (injective and surjective) function . Since its element of the Range is 4, then its corresponding one on the Domain set is 2.
