What does a mapping diagram illustrate?
C
A mapping diagram illustrates how each element in the input is paired with an element in the output. An ordered pair is a set of numbers written in the form (x,y), where x is a number from the input and y is a number from the output.
Looking at where the arrows start and end, we can see the x-coordinates and their corresponding y-coordinates. We get the ordered pairs by pairing these values. (1,0), (2,2), (2,- 2), (3,- 2) This corresponds to option C.
