solve for vertex, axis of symmetry, y-intercept.\r
\n" ); document.write( "\n" ); document.write( "(y=(1/2)x^2 + 4X + 3)
\n" ); document.write( "-----------------------
\n" ); document.write( "Vertex and axis of symmetry occur where x = -b/2a = -4/(2*1/2)= -4
\n" ); document.write( "f(-4) = (1/2)16 -16+3 = -5
\n" ); document.write( "------------------------------
\n" ); document.write( "y-intercept occurs where x = 0: y = 3
\n" ); document.write( "======================================
\n" ); document.write( "Vertex: (-4,-5)
\n" ); document.write( "Axis of sym: x = -4
\n" ); document.write( "y-intercept: y = 3
\n" ); document.write( "===========================
