In set notation, what does the expression {x:x>3}\{x:x>3\}{x:x>3} mean?
x>3x > 3x>3
The coordinates of the intersection points where the graphs meet.
The set of values of xxx such that xxx is greater than 3.
Solve each separately and find the overlap (intersection) of the two sets.
Flashcards for Edexcel A Level Maths Equations and Inequalities, covering the key formulae, methods and definitions you need to recall for Paper 1, Paper 2 and Paper 3. 23 cards drawn from 3.1 Linear Simultaneous Equations, 3.2 Quadratic Simultaneous Equations, 3.3 Simultaneous Equations on Graphs, 3.4 Linear Inequalities, 3.5 Quadratic Inequalities, and 3.6 Inequalities on Graphs, 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.
