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 ...

ROLLERCOASTER RIDE: Desmos is up to more math goodness with the recent addition of Function Carnival, developed in collaboration with Dan Meyer and Christopher Danielson. Function Carnival helps ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) ...

In the applet below is intended to help you understand the connection between the graph of a function and the function itself. Recall that a function can be thought of as a machine which takes an ...

Hash functions are a one-way mathematical problem. If a person has the resulting hash, it is impossible to convert it back to the original data. In this episode of “Bitcoin, Explained,” hosts Aaron ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c\) is a smooth curve with one turning point. The turning ...
