\n" ); document.write( "Hi\r
\n" ); document.write( "\n" ); document.write( "p(x)=x^2-2x+5
\n" ); document.write( "Using the vertex form of a parabola, \"y=a%28x-h%29%5E2+%2Bk\" where(h,k) is the vertex
\n" ); document.write( "completing the square to put into vertex form
\n" ); document.write( "p(x) = (x-1)^2 + 4 vertex Pt(1,4) is a minimum pt, a>0, parabola opens upward
\n" ); document.write( "Although the range of p(x) is p(x)>= 4, the domain x-values are all real numbers
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
