1 answer
Yes, the set of points (1,3), (2,1), (3,1), (4,7) forms a function. For a set of points to be a function, each x-value (input) can only correspond to one y-value (output). In this case, each x-value is unique and corresponds to only one y-value, so it satisfies the definition of a function.
