You can put this solution on YOUR website!
Let $\"+y=sqrt%28x-7%29+\"$ then re-arrange to make $\"+x+\"$ the subject
\n" ); document.write( " $\"+sqrt%28x-7%29+=+y\"$
\n" ); document.write( " $\"+y%5E2+=+x-7\"$
\n" ); document.write( " $\"+x=y%5E2%2B7+\"$
\n" ); document.write( "this is the inverse function, so $\"+f%5E%28-1%29%28x%29=x%5E2+%2B+7+\"$ \n" ); document.write( "

\n" );
