Typical office paper is 80 to 90 GSM, as a reference point, and you’ll find most notebooks stay within a 56 to 120 GSM range. Paper weight plays a huge part in how well the pages can handle ink.

If the graph of the quadratic function y = a x 2 + b x + c crosses the x-axis, the values of x at the crossing points are the roots or solutions of the equation a x 2 + b x + c = 0.

Translations parallel to the y-axis If f (x) = x 2, then f (x) + a = x 2 + a. Here we are adding a to the whole function. The addition of the value a represents a vertical translation in the graph.

Like graph paper, a cell can equal anything you want. The hard part is getting the width and height settings to produce a square because there’s no easy way to match a cell’s height and width ...
