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).

this problem is referencing set V, which we saw back and exercise seven. Now for this problem, we're going to define two sets. We want to define the domain and the range for set V. So let's look a domain first. The domain of a of a function or a set are the inputs, the numbers that go in to it. What we have ordered pairs. That input number is the first number or the X values in my ordered pair. So let's look at Set V. What do I have for inputs or X values? I have a four of five of four and a nine, even though four appears twice, I Onley have toe list it once in my domain set. We don't have thio kind of messy. I don't have to do anything to indicate that it shows up more than once. Just that it exists as an input is all I need to show in the domain. So my domain has three numbers in it. 45 and nine. What about range? Well, if domain is my input range is my out put the values that I get out of my function or it's the second number in a non ordered pair in a set like V, the second number R R Y values. So let's look at set V. My second numbers. My wife values are 237 and negative 22 and typically we write the's in ascending order. It's alright, Negative 22 to 3 and seven. So this is my domain and my range for set V.
