It not only scans your equation and gives a mathematical answer, but it gives you reasoning behind how it's solved too! Not all relations are functions, and not all functions are relations. Domain: \([5, 1]\); range: \([2, 2]\); function: no, 25. 15If any vertical line intersects the graph more than once, then the graph does not represent a function. Legal. endstream A relation with this property is called a function14. RELATIONS & FUNCTIONS Worksheet. \(g (4) = 3, g (2) = 0\), and \(g (6) = 2\). Then graph the function and its inverse.
