$\"g%28x%29=1%2F%282x-1%29\"$
\n" ); document.write( "To find an inverse function, switch y and x in the expression and solve for y.
\n" ); document.write( " $\"y=1%2F%282x-1%29\"$
\n" ); document.write( " $\"highlight%28x%29=1%2F%282highlight%28y%29-1%29\"$
\n" ); document.write( " $\"x%282y-1%29=1\"$
\n" ); document.write( " $\"2y-1=1%2Fx\"$
\n" ); document.write( " $\"2y=1%2Fx%2B1\"$
\n" ); document.write( " $\"2y=1%2Fx%2Bx%2Fx\"$
\n" ); document.write( " $\"2y=%281%2Bx%29%2Fx\"$
\n" ); document.write( " $\"y=%281%2Bx%29%2F2x\"$
\n" ); document.write( "Yes, it is a function. There is only one y value for each x value.
\n" ); document.write( " \n" ); document.write( "
