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 a function. G and G is a set off four distinct points. And the question that we're asking here is is g ah function. So in order to answer this, we need to look at the definition of a function. What do we mean when we call something a function? Well, a function is a set of ordered pairs. Um so we have two numbers that go together where every input has exactly one output. So every number in goes exactly one place. Okay. In other words, let's do some numbers with this. Let's say 10 was an input for a function and we could say maybe 10 goes to 20. It would not also go to 30. It can't go to two places. Every input has to go just one place. So let's take a look at the function. We've been given our look at G and see if it's a function. So let's look at our inputs. 237 and five. Those air all distinct numbers, so there is no confusion. Each one of those inputs has exactly one output to goes to negative 53 goes to 47 goes to 95 goes to 11. Every input has exactly what output. So, yes, this is indeed ah function.
