Answer:
Option: C is the correct answer.
No, because one x-value corresponds to two y-different values.
Step-by-step explanation:
Function--
A mapping from a set A to set B is said to be a function if each element of set A is mapped to a single element of set B.
i.e. no element of A has more than one image.
i.e. the set of ordered pair (x,y) represent a function if every x-corresponds to just one y-value.
The table of values is given by:
x y
2 1
3 4
4 4
5 2
5 5
This table does not represent a function because the element 5 has 2 images.
i.e. the ordered pair (5,2) and (5,5) represents that 5 is mapped to 2 and 5 is mapped to 5 as well.
