Determine whether the relation defines to be a function of . If a function is defined, give its domain and range. If it does not define a function, find two ordered pairs that show a value of that is assigned more than one value of . See Example 2.$$\begin{array}{|c|c|}\hline x & {y} \\\hline 1 & {1} \\{2} & {2} \\{3} & {3} \\{4} & {4} \\\hline\end{array}$$
Domain $=(1,2,3,4)$Range $=(1,2,3,4)$

in this problem forgiven the valid table of values that represents a relation. So the first thing were asked to do is determine whether this relation is a function will remember. If it's a function, every X value will be assigned to a different y value. If you know this in this case, every single X value is mashed with a different Y value. They're forthis is a function Well, then our directions going to say, if it is a function to find the domain in the range. So let's start with the dummy. Well, remember, the domain represents the set of all of our first components. Well, remember, the first components are just our X values. So in this case, our domain is the set off. 123 and four all of our X values. Now let's find the range. Well, remember, the range represents the set of all of the second components in the relation will remember, The second components are just R Y values, so our range in this particular case will be one, 23 and four
