Start with the original graph
Start with the original graph
The graph y=f(x)y=f(x)y=f(x) is the original function. If the graph contains the point (3,6)(3,6)(3,6), then when the input is 3 the output is 6, so f(3)=6f(3)=6f(3)=6.
Step-by-step lessons covering Edexcel IGCSE Maths Transforming Graphs y=f(x) for IGCSE Maths. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Build confidence with the shared Foundation-tier content first, since roughly 40% of Higher-tier marks are targeted at the grades 4–5 boundary that both tiers have in common.
