Following are some integers that satisfy both equations: Here two relations consisting of seven ordered pair solutions are obtained: \(y=|x|2hassolutions\{(3,1),(2,0),(1,1),(0,2),(1,1),(2,0),(3,1)\}\), \(x=|y|+1hassolutions\{(4,3),(3,2),(2,1),(1,0),(2,1),(3,2),(4,3)\}\). A vertical line can cross the graph of \(x=|y|+1\) more than once; therefore, it is not a function. 16The notation \(f (x) = y\), which reads \(f\) of \(x\) is equal to \(y\). Given a function, \(y\) and \(f (x)\) can be used interchangeably.
