You can put this solution on YOUR website!
Use x,y.
\n" ); document.write( " $\"y=2%283x%2B1%29%5E2\"$
\n" ); document.write( "Interchange x and y and solve for the new y.
\n" ); document.write( "That new y is the inverse.
\n" ); document.write( " $\"x=2%283y%2B1%29%5E2\"$
\n" ); document.write( " $\"x%2F2=%283y%2B1%29%5E2\"$
\n" ); document.write( " $\"3y%2B1=0+%2B-+sqrt%28x%2F2%29\"$
\n" ); document.write( " $\"3y=-1+%2B-+sqrt%28x%2F2%29\"$
\n" ); document.write( " $\"y=-1%2F3+%2B-+%281%2F3%29sqrt%28x%2F2%29\"$
\n" ); document.write( " $\"f%5E%28-1%29%28x%29=-1%2F3+%2B-+%281%2F3%29sqrt%28x%2F2%29\"$
