An Elliptical cone along $y$-axis as represented by $\bf{Graph(h)}$

Work Step by Step

Given: $x^2+4z^2=y^2$ ...(1) Re-write as: $\dfrac{x^2}{1}+\dfrac{z^2}{(1/2)^2}=\dfrac{y^2}{1}$ ...(2) Hence, the equation (2) shows a graph for an Elliptical cone along $y$-axis as represented by $\bf{Graph(h)}$
