You can put this solution on YOUR website!
we know this parabola will open downward as the a is negative. so this will have a maximum
\n" ); document.write( ":y=a(x-h)+k.....(h,k) is the vertex
\n" ); document.write( ":
\n" ); document.write( "axis of symmetry is x=h
\n" ); document.write( ":
\n" ); document.write( "max min value is y=k
\n" ); document.write( ":
\n" ); document.write( " $\"y=-x%5E2%2B4\"$
\n" ); document.write( ":
\n" ); document.write( "vertex is at (0,4)
\n" ); document.write( ":
\n" ); document.write( "line of symmetry is x=0. line of symmetry is nothing more than the line that splits the parabola in half
\n" ); document.write( ":
\n" ); document.write( "max is y=4
\n" ); document.write( ":
