Answer:
Yes - A.
Step-by-step explanation:
Yes, because of the information given below the question, as follows:
Does each input (x) give you one output (y)?
So, therefore, the following pairings would not represent a function:
x y
1 2
1 3
Since the x-value of 1 is paired with more than one output.
If you plug in values in an x-y table that follow this rule, you'll see that one x-value cannot be paired with two different y-values:
x y
-2 -1/2
-1 -1/4
0 0
