A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight line or a smooth curve. A linear function has an equation of the form \ (y = mx + c\).

Sketch derived, inverse or other related functions using graph translations. Complete the square and find composite functions for Higher Maths.

We study the pluripolar hull of the graph of a holomorphic function f, defined on a domain D ⊂ ℂ outside a polar set A ⊂ D. This leads to a theorem that describes under what conditions f is nowhere ...

Many types of economic problems require that we consider two variables at the same time. A typical example is the relation between price of a commodity and the demand or supply of that commodity. The ...
