You can put this solution on YOUR website!
using the vertex form of the quadratic ___ y = a(x - h)^2 + k ___ (h,k) is the vertex\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = a(x - -4)^2 + 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting the given point to find a ___ 3 = a(-6 + 4)^2 + 7 ___ -4 = 4a ___ -1 = a\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = -(x + 4)^2 + 7 \n" ); document.write( "
