We are going to do this step by step:
Let's start with option A
A.
X = 25 and Y = 5/2
In this case, when X = 25 , then Y = 10 ,which is different to 5/2
B.
X = 14 , Y = 35
In case, when X = 14, then Y = 28/5, which is different to 35
C.
X = 40 , Y = 24
Similarly, in this case, when X = 40, then Y = 16, which is different to 24
D.
X = 10 , Y=4
Now, in this case, we can see that when X = 10, then Y = 4 which is the same as the given value of Y
E.
X = 50 , Y = 20
In this case, the values of Y are also the same.
F.
X = 30 , Y = 12
Again, in this case, the values of Y are the same, so the pair satisfies the equation.
In conclusion: options D, E and F satisfy the equation
Answer: Option B.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, a relation is a function if and only if each input value has an unique output value.
The input values are the values of the variable "x" and the output values are the values of the variable "y".
You can observe in the table shown in the picture, that the input value -2 has two different output values:
Notice that the input vale -1 has two different output values too:
Therefore, based on this, you can conclude that the information given in the table is a relation but not a function.
