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

Abstract. 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 ...

Functions are one of the most fundamental concepts in mathematics, serving as a cornerstone for topics in algebra, calculus and beyond.Basics of functions are stepping-stone to success in functions ...
