You can put this solution on YOUR website!
f(x) = 11(x-5)^2 +7
\n" ); document.write( "=11(x^2-10x+25)+7
\n" ); document.write( "=11x^2-110x+275+7
\n" ); document.write( "=11x^2-110x+282
\n" ); document.write( "a=11, b=-110, c=282
\n" ); document.write( "It has a minimum because a is positive.
\n" ); document.write( "axis of symmetry: x =-b/2a = 110/22 = 5
\n" ); document.write( "y=11(5-5)^2 +7 =7
\n" ); document.write( "coordinates of the vertex (5,7)
