$${\text{parabola}}$$

$$\eqalign{ & 4{x^2} - y = 0 \cr & {\text{Add }}y{\text{ to both sides if the equation}} \cr & 4{x^2} = y \cr & {x^2} = \frac{1}{4}y \cr & {\text{The equation is written in the form }}{x^2} = 4py \cr & {\text{Therefore,}} \cr & {\text{The graph of the equation is a parabola}} \cr} $$
