Sketch the graph with equation
y=∣2x−3∣ y = |2x - 3| y=∣2x−3∣stating the coordinates where the graph meets the coordinate axis.
Find the values of x x\,x which satisfy ∣2x−3∣<9|2x - 3| < 9∣2x−3∣<9
Find the values of x x\,x which satisfy ∣2x−3∣<x+1|2x - 3| < x + 1∣2x−3∣<x+1
Practise Edexcel A Level Maths Functions and Graphs with exam-style questions for A Level Maths. 100 questions covering 2.1 The Modulus Function, 2.2 Functions and Mappings, 2.3 Composite Functions, 2.4 Inverse Functions, 2.5 y=|f(x)| and y=f(|x|), 2.6 Combining Transformations, and 2.7 Solving Modulus Problems, matched to the Edexcel A Level Maths (9MA0) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
