Graphing the Function f(x) = x^2

I plotted 6 different points that satisfied the equation f(x) = x ² starting with 1 as the value of x.

The curved line would cross the y-axis at the point (0, 0) but this curved line segment does not show that because the first value of x that I plotted was 1. If I had started with -1 then the curved line segment would have crossed the y-axis. I thought about how that would look and it would be the reflection of the curve I have plotted with the y-axis as the line of reflection.

This is steep. The values for f(x) get large quite quickly.
