IB skill practice

Interpret transformations in vertex form

Read vertex form of a quadratic to identify translations, reflection, vertical stretch, vertex, axis of symmetry, y-intercept, and range.

Paper 1 5 marks Difficulty 2

Use transformations to state range

For \(g(x)=2(x + 4)^{2} - 4\), state the opening direction, vertex, and range. Justify the range using the transformation.

Worked practice: quadratic features

Use the vertex-form information to state the graph features in order.
