6 0 obj Math Worksheet 1- FUNCTION versus RELATION Relations . There are many \(x\)-values in the domain that correspond to two \(y\)-values. State the domain and range of a relation. The previous example, where \(g (x) = x^{2}\), illustrates this nicely, \(\begin{array} { l } { g ( x + h ) \neq g ( x ) + g ( h ) } \\ { ( x + h ) ^ { 2 } \neq x ^ { 2 } + h ^ { 2 } } \end{array}\). In this case, we interpret \(f(5) = 3\) as follows: Function notation streamlines the task of evaluating. Given \(g ( x ) = x ^ { 2 }\), find \(g (2), g ( \frac{1}{2} )\), and \(g (x + h)\). 4.2 Relations and Functions A function is a relation in .
