State whether the following rule defines y as a function of x or not. 0 1 - 2 -3 3 - 9 - 19 X y 3 - 19 2 Is y a function of x? 9 1 3 1 - O A. Yes, because each x-value of the given rule corresponds to exactly one y-value. B. No, because at least one x-value of the given rule corresponds to more than one y-value. O C. No, because at least one y-value of the given rule corresponds to more than one x-value. O D. Yes, because each y-value of the given rule corresponds to exactly one x-value.
