How are the x-intercepts and y-intercept of a graph y=f(x)y=f(x)y=f(x) found?
Solving the inequality f(x)>0f(x) > 0f(x)>0 using a sketch means finding the values of xxx where the graph is above the x-axis.

Flashcards for Edexcel A Level Maths Graphs and Transformations, covering the key formulae, methods and definitions you need to recall for Paper 1, Paper 2 and Paper 3. 25 cards drawn from 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, matched to the Edexcel A Level Maths (9MA0) specification. Recall questions account for roughly 50% of marks at A Level Maths, so these target the marks you can secure before the paper starts.
