A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a large number of set intervals, it is ...

In this video, we provide essential "math help" by explaining how to "graph" piecewise functions. This "math tutorial" breaks down what is a function into its component parts, explaining the ...

👉 Learn how to graph piecewise functions. A piecewise function is a function which has more than one sub-function for different sub-intervals (sub-domains) of the function's domain. To graph 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 ...
