Modulus Functions Past Paper Questions (iGCSE Additional Maths Cambridge 0606)

Studying for your Additional Maths iGCSE?

On this page you'll find plenty of questions on modulus functions from Cambridge iGCSE past papers.

Students should understand how to interpret and sketch graphs of equations in the form y = |f(x)|, where f(x) can be linear, quadratic, cubic, or trigonometric.

They are expected to solve equations involving modulus expressions such as |ax + b| = c and |ax + b| = |cx + d| using both algebraic and graphical methods.

Questions may also include solving modulus inequalities, for example k|ax + b| ⩽ c or |ax² + bx + c| > d, where students must interpret solutions carefully using appropriate methods.
