Answer:

C. No, more than one output value x is assigned to the input y-value

Step-by-step explanation:

Given

х у

-3 -2

3 6

0 7

1 7

2 4

3 - 1

Required

State if the table shows x as a function of y

x being a function of y means

[tex]x = f(y)[/tex]

i.e. x represents the output while y represents the input of the function

Note that each value of y (input) must be assigned to separate values of x (output) for a function to be established

Having said;

Next step: We have to examine the x and y column

In the y column, the value 7 occurred twice (as shown below)

х у

0 7

1 7

This implies that;

Input 7 gives output of 0 and 1.

Hence, this is not a function.

Option C answers the question.
