In this video, I demonstrate how to quickly find the "x and y intercepts" of "quadratic equations" by inspection. We'll go ...

👉 Learn how to graph piecewise functions. A piecewise function is a function which has more than one sub-function for ...

An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight ...
