The equation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9ef0db6cc9a444224da1effaa96be48c.png\")
.
The above equation represent a x - axis (y = constant). So, there is need not make the table.
\Graph for the equation ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9ef0db6cc9a444224da1effaa96be48c.png\")
on a coordinate plane.

The graph is a line.Place a pencil at the left or right of the graph to represent a vertical line. Slowly move the pencil across the graph.
\For any value of x, the vertical line passes through no more than one point on the graph. So, the graph and the equation represent a function. ![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
Yes, the relation is a function.
