IB skill practice

Identify key features of quadratic functions

Find intercepts, axis of symmetry, vertex, domain, and range from a quadratic in expanded or factorised form, with solution language suitable for IB markschemes.

Paper 1 6 marks Difficulty 3

Compare expanded and factorised information

The same quadratic can be written as \(f(x)=2x^{2} - 16x + 24\) and \(f(x)=2(x - 2)(x - 6)\). Use the most useful form to find the \(x\)-intercepts, \(y\)-intercept, axis, vertex, and range.
