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 ...

This study adopted a content-analysis method to examine the differences in how the topic of functions was handled by Finnish, Singaporean, and Taiwanese middle-grade mathematics textbooks for children ...

In this video, we provide essential "math help" by explaining how to "graph" functions, beginning with a basic cosine wave and then moving on to a piecewise function. This "math tutorial" demonstrates ...

The first handheld graphing calculator, the Casio fx-7000G, appeared in 1985. Since then, graphing calculators have become a common – and controversial – tool for learning mathematics. These devices ...

A translation is a shift of the graph either horizontally parallel to the \(x\)-axis or vertically parallel to the \(y\)-axis. If \(f(x) = x^2\), then \(f(x) + a = x^2 + a\). The value of \(a\) ...

If \(f(x) = x^2\), then \(af(x) = a(x^2)\). This tells us that we need to multiply each of the \(y\) coordinates on the graph by \(a\) in order to stretch the ...
