If \(f(x) = x^2\), then \(-f(x) = -(x^2)\). This means that each of the \(y\) coordinates will have a sign change. So \(y = 4\) would become \(y = -4\), and \(y = -1 ...

Abstract: Graph signal processing has been shown to provide a unique platform and new perspective for representing and analyzing power system measurements. In this paper, the effects of various cyber ...

A straight line drawn on a grid can be described by a rule connecting the x and y coordinates of every point on the line. This is known as the equation of the line. The equation of any straight line ...
