You can put this solution on YOUR website!
f(x)=x^2-x+9
\n" ); document.write( "x=-(A/B) [formula for the x-value of the vertex]
\n" ); document.write( "x=-(1/-1)=1
\n" ); document.write( "f(x)=(1)^2-(1)+9 [plug-in x=1 and solve for f(x) or y]
\n" ); document.write( "f(1)=1-1+9
\n" ); document.write( "f(1)=9
\n" ); document.write( "So, the vertex is (1, 9)\r
