f(x)=x^2+2x-4 Give the vertex, axis, domain, and range.
\n" ); document.write( "***
\n" ); document.write( "f(x)=x^2+2x-4
\n" ); document.write( "complete the square:
\n" ); document.write( "f(x)=(x^2+2x+1)-1-4
\n" ); document.write( "f(x)=(x+1)^2-5
\n" ); document.write( "This is an equation of a parabola that opens upward.
\n" ); document.write( "Its standard (vertex) form of equation: y=(x-h)^2+k, (h,k)=coordinates of the vertex
\n" ); document.write( "For given parabola:
\n" ); document.write( "vertex: (-1,-5)
\n" ); document.write( "axis of symmetry: x=-1
\n" ); document.write( "Domain: (-∞,∞) or all real numbers
\n" ); document.write( "Range: (-5,∞)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
