Change from general form into standard form and you will see what happened to a and k. Look for the lesson on this, involving Completing the Square.\r

\n" ); document.write( "c changed from 0 to 22. General form would be from \"ax%5E2%2Bbx%2Bc=y\". Usual symbolism for stating standard form is \"y=a%28x-h%29%5E2%2Bk\".
