Answer
Please see the graph.
Work Step by Step
$h(x) = 1/3*x^2$
Axis of symmetry:
$h(x) = 1/3*x^2$
$h(x) = 1/3*(x-0)^2$
$x=0$
Vertex:
$h(x) = 1/3*x^2$
$h(0) = 1/3*0^2$
$h(0)= 1/3*0$
$h(0)=0$
The red line is the function $h(x) = 1/3*x^2$, the dot at $(0,0)$ is the vertex, and the orange line at $x=0$ is the axis of symmetry.
