The formula "Y is a function of X" means that the value of Y can be explained in terms of how X varies. In other words, as X changes, it has an effect on Y, and we can use X to predict or explain the values of Y. Choice A is incorrect because it implies that X is the dependent variable when in fact it is Y that is dependent on X. Choice B is incorrect because it implies that there is no relationship or connection between X and Y. Choice D is incorrect because it suggests that X and Y are numerically equal, which is not necessarily true in a function.
