The answer is 0.3 thanks for the points
Identify the relation that is also a function. A. {(-1, 1) (0, 0) (1, 1) (2, 4)} B. {(3, 4) (2, 3) (3, 6) (2, 0)} C. {(1, 0) (2,
madreJ [45]
Answer:
Step-by-step explanation:
We are given four sets of relations as
A function is a relation in which every element in the first set has a unique image in the second set.
Let us check this aspect to A.
This is a function
Now come to B. 3 has two images 4 and 6. so not a function
Next is C. in C 1 has two images 0 and 6. So not a function
For D, 3 has 4 images so not a function.
