The graph was made using graphing software. The vertex is labeled with the coordinates, and the red line is the axis of symmetry. vertex: $y=.5x^2+2x+1$ $V = -b/2a = -(2)/2(.5)$ $V = -2/1 = -2$ $y=.5x^2+2x+1$ $y=.5(-2)^2+2(-2)+1$ $y=.5*4+-4+1$ $y=2-3 = -1$ (-2, -1) $x=-2$ is the axis of symmetry One other point on the graph: $y=.5x^2+2x+1$ $y=.5(0)^2+2(0)+1$ $y=.5*0+0+1$ $y=0+0+1=1$ (0,1)
