Reading a graph
Reading a graph
A graph of y=f(x)y=f(x)y=f(x) shows all points (x,y)(x,y)(x,y) that satisfy the rule. In sketch questions, your first aim is to find the key features you can label exactly.
Step-by-step lessons on Edexcel A Level Maths Graphs and Transformations, covering 4.1 Cubic Graphs, 4.2 Quartic Graphs, 4.3 Reciprocal Graphs, 4.4 Points of Intersection, 4.5 Translating Graphs, 4.6 Stretching Graphs, and 4.7 Transforming Functions. Each one builds up to exam-style questions. Build fluency with the core pure algebra and calculus toolkit early, since almost every mechanics and statistics topic on the course depends on it.
