See explanation

This is a quadratic in $y$ instead of in $x$ . Thus the axis of symmetry is parallel to the y-axis.

As the $y^2$ term is positive the general form of the graph is $sub$ . Negative would give $sup$

As there is no constant or $y$ term the graphs axis of symmetry is the x-axis and the vertex is at $(x,y)=(0,0)$

The coefficient of $y^2$ is greater than one so it has the effect of widening (vertically) the $x=y^2$
