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 ...

Commutative algebra and graph theory are two vibrant areas of mathematics that have grown increasingly interrelated. At this interface, algebraic methods are applied to study combinatorial structures, ...

This paper presents a conceptual analysis for students' images of graphs and their extension to graphs of two-variable functions. We use the conceptual analysis, based on quantitative and ...

For 12-year-old Rylee Anderson, the algebra concept of graphing a function just didn’t make sense. Since her classes are now all remote due to the coronavirus pandemic, Anderson emailed her teacher ...

The women behind "Moebius Noodles: Adventurous Math for the Playground Crowd" are back with another fun math game they call Function Machines. I introduced Maria Droujkova and Yelena McManaman last ...
