Answer
PLot with points as mentioned below
Work Step by Step
Plot $y^2 = x$
Observation
1. $(0, 0)$ lies on the graph
2. $x = y^2$ so x will always be positive
3. $+y, -y$ will gave same x, so graph symmetric about x-axis
4. Graph will be a parabola as it is of the form $y^2 = 4ax$
5. Plot the graph with y = 0, 1, 2, 3 and finding corresponding x and then take mirror image about x-axis
