\n" ); document.write( "If \"f%28x%29=x%5E2-3\" and \"f%28a%29=46\", the value of \"a\"is: \r
\n" ); document.write( "\n" ); document.write( " \"46=x%5E2-3\"......solve for \"x\"\r
\n" ); document.write( "\n" ); document.write( " \"46%2B3=x%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"49=x%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"x=sqrt%2849%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x=7\" or \"x=-7\"=>\"a=7\" or \"a=-7\"
