Determine if the equation specifies a function with independent variable x. If it does, find the domain. If it does not, find a value of x to which there corresponds more than one value of y.

x2+y2=16

Does the equation specify a function with independent value x?

Yes or No

Based on your answer above, provide either the domain of the function or a value of x to which there corresponds more than one value of y.

A. The domain of the function above is all real numbers.

B. A counterexample is x equals =4

C. A counterexample is x equals =6

D. A counterexample is x equals =0.
