#### Answer

Refer to the image below for the graph.

#### Work Step by Step

Divide both sides of the equation by $4$ to obtain:
$\dfrac{4y}{4}=\dfrac{-x^2}{4}
\\y = \dfrac{-x^2}{4}$
To graph the given equation, perform the following steps:
(1) Create a table of values by assigning values to $x$ then solving for the corresponding value of $y$ for each one.
(Refer to the attached image below)
(2) Plot each ordered pair from the table of values then connect the points using a smooth curve to form a parabola.
