Unformatted text preview: On the graph of g above, the only point with ycoordinate 9 has xcoordinate 3. More generally, g x ( ) = b has a unique solution for x , the unique input that yields b , whenever b is in Range g ( ) , which is 0, ) . We can define a unique inverse function g 1 . Let Dom g 1 ( ) = Range g ( ) , which is 0, ) . Define g 1 b ( ) to be the unique solution to g x ( ) = b , for every b in Dom g 1 ( ) . For instance, g 1 9 ( ) = 3 . (In Example 1, since f ( ) = 32 , we reverse the arrow and define f 1 32 ( ) to be 0.)...
