In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x^2. The output of a function f corresponding to an input x is denoted by f(x).

for this problem. We have been given Set V and V is comprised of four distinct points and we're gonna be answering the question in this exercise is v ah function. To answer that, we need to look at the definition of function. Ah, function is a set of ordered pairs such that each first element of the ordered pair corresponds to a unique second element in the ordered pair. In other words, every input goes to exactly one output and we can also show this with a number. Example. Let's say I have to is an input and it goes to three well to could not also go to four. That would mean I would have to different outputs and I need exactly one. So I could Onley have two. Could Onley go toe one place Every input has exactly one output. So let's take a look at the set V that we've been given. If you look at thes X values, you'll notice that we have two that are the same. Okay, I have a five and a night as well, but I have two that are the same. So in order to be a function, four can only go toe one output. But for the first case, four goes to to In the second case, four goes to seven. This is not exactly one output, so no, this is not ah function.
