to find an inverse of \"f%28x%29=2x%2B7\", first recall that \"f%28x%29=y\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=2x%2B7\" now swap \"x\" and \"y\"\r
\n" ); document.write( "\n" ); document.write( "\"x=2y%2B7\"....solve for \"y\"\r
\n" ); document.write( "\n" ); document.write( "\"x-7=2y\"\r
\n" ); document.write( "\n" ); document.write( "\"%28x-7%29%2F2=y\"\r
\n" ); document.write( "\n" ); document.write( "so, inverse is:\r
\n" ); document.write( "\n" ); document.write( "\"f%5E-1%28x%29=%28x-7%29%2F2\"\r
