To check whether the equation defines y as a function of x or not, we need to verify if for each x value there exists only one y value. In other words, for each input x, we should get only one output y. 
In this case, we can see that for any value of x, there is only one corresponding value of y given by the square root of 6x-2. Therefore, the equation defines y as a function of x.
