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 ...

Jean Kelly from Dublin's Institute of Education is here with six videos full of great advice and tips for the exam.

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 ...

Data from an experiment may result in a graph indicating exponential growth. This implies the formula of this growth is \(y = k{x^n}\), where \(k\) and \(n\) are constants. Using logarithms ...

If you understand the definition of a mathematical function, a good way to judge it ... whether you use it simply with marking points or lines, the graph is spread across the XY-axis.
