There's more to your application than just filling out the forms. As a check, we can evaluate \(f (4) = 5 (4) + 7 = 27\). The Vertical Line Test: Given the graph of a relation, if a vertical line can be drawn that crosses the graph in more than one place, then the relation is not a function. 2-1 Skills Practice. <> %PDF-1.3 % With the definition of a function comes special notation. As every value of x has a different value of y; it is a function. The correspondence between the domain and range of each can be pictured as follows: Notice that every element in the domain of the solution set of \(y = |x| 2\) corresponds to only one element in the range; it is a function. These multiple representation tasks help students see the connections between the equation, table of values, and graph. This is because a person has just one height value at any time in their life. As we can see, any vertical line will intersect the graph of \(y=|x|2\) only once; therefore, it is a function.
