$\"y-k=a%28x-h%29%5E2\"$
\n" ); document.write( "Plug the vertex in for (h,k)
\n" ); document.write( " $\"y-%28-5%29=a%28x-1%29%5E2\"$
\n" ); document.write( " $\"y%2B5=a%28x-1%29%5E2\"$
\n" ); document.write( "Now use the point (-4,3) to solve for $\"a\"$ .
\n" ); document.write( " $\"3%2B5=a%28-4-1%29%5E2\"$
\n" ); document.write( " $\"8=a%28-5%29%5E2\"$
