Forming Inequalities · Feasible Regions · Objective Functions · Optimisation
Based on your Form 4 Notes — including all KCSE past questions
This interactive covers everything in your Form 4 notes: forming inequalities from real-life situations (Esha's age, books and pens, cement contractor, gadget company), graphing to find feasible regions, writing objective functions, and optimising by testing corner points. The Hard stage uses actual KCSE exam questions from your notes. Each question shows a full worked explanation after you answer.
