Also..........the derivative of the square function is...........2x............................2..........like 2 pi....connecting East and West.........West and East.......reflexive sym..........the critical line......is vertical...........the so called trivial zeros.......along the X axis horizontal.........they are perpendicular to each other..........at a 90 degree angle......................and one is in the East and one in the West.........sym.....

Square Function

This is the Square Function:

f(x) = x²

This is its graph:

f(x) = x²

It is a Parabola.

It has symmetry about the y-axis (like a mirror image).

And it is an even function.
