Answer

Please see the graph.

Work Step by Step

$h(x) = (x+1)^2+4$ Axis of symmetry: $h(x) = (x+1)^2+4$ $h(x) = (x- -1)^2+4$ $x=-1$ Vertex: $h(x) = (x+1)^2+4$ $h(-1) = (-1+1)^2+4$ $h(-1)=0^2+4$ $h(-1) = 0+4$ $h(-1)=4$ The green line $x=-1$ is the axis of symmetry, the black dot at $(-1,4)$ is the vertex, and the red line is the function $h(x)=(x+1)^2+4$.
