👉 Learn how to find the value that makes a function continuous. When given a piecewise function which has a hole at some ...

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

Expressions are a useful tool, however they can become confusing as the variables all are global. Changing x changes the value of any expression involving x. This is not usually how we want things to ...

This example illustrates some properties of splines. Splines are curves, which are usually required to be continuous and smooth. Splines are usually defined as piecewise polynomials of degree n with ...
