In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following ...

When you see a flat line on a graph, it’s tempting to think ... But we come to these charts with some assumptions, and we often don’t read the title and axes very carefully.

Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing graphs as functions in the form of \(f(x)\) is useful ...

A bar graph represents the data of an Excel sheet in an easy-to-read visual graphic. There are several types of bar graphs that work for different data sets. When collecting, analyzing ...
