I believe it’s C, because in a recursive rule you must have (n-1), this shows that you’re using the previous term to solve for the next one.
The second one because for every x value there is one and only one y value. If you plotted the points and graphed it, you would know it is not a function if it doesn't pass the vertical line test. Notice the same x values show up repeatedly in the other ordered pairs with different y values. Only one y value for every x value
