Refer Explanation Section.

Given -

$y=-x^2$

There is no constant term in the given equation. Hence it passes through the origin.

Take a few points less than and greater than zero. These are the likely values variable $x$ is going to assume. Find the corresponding values of $y$

Tabulate them as follows.
