Inverse each given function; then determine whether the result is a function. 1. A={(2,8);(3,7);(9,8)} a.___ b.___
\n" ); document.write( "Inverse: (8,2)(7,3)(8,9)
\n" ); document.write( "Not a function because there are two different y values when x = 8
\n" ); document.write( "--------------------------------------------------------------
\n" ); document.write( "2. C={(4,5;(5,4);(-4,5)} a.___ b.___
\n" ); document.write( "Inverse: (5,4)(4,5)(5,-4)
\n" ); document.write( "Not a function because there are two different y values when x = 5
\n" ); document.write( "----------------------\r
\n" ); document.write( "\n" ); document.write( "3. E={(4,1);(1,3);(-2,5)} a.___ b. ____
\n" ); document.write( "Reverse each ordered pair to form the inverse.
\n" ); document.write( "This one will be a function because each x value will have only one y value
\n" ); document.write( "-----------------------
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "3. G= {(2,0);(0,1);(-3,2)} a____ b ____
\n" ); document.write( "Same process.
\n" ); document.write( "This inverse will be a function.
\n" ); document.write( "=====================
