Edexcel IGCSE Math A Higher 1.5.HA Algebraic Sets & Subsets

Edexcel IGCSE Math A syllabusMath A 4MA1First assessment 2018

Practise listing members of sets defined by algebraic conditions and constructing sets that satisfy subset restrictions.

How this is tested

test each candidate value against the algebraic condition before listing the set
distinguish membership from subset notation when interpreting a condition
construct one valid set whose elements and subset relations satisfy every restriction
