Determine whether the equation y=313x defines y as a function of x. 13 Does the equation y = 3 x define y as a function of x? OA. Yes, because for any input x, the equation yields only one output y. OB. Yes, because any equation in terms of x and y is a function. OC. No, because for any input x, the equation yields more than one output y. OD. No, because for any input x, the equation yields only one output y.
