GCSE Maths Practice: graph-transformations

Question 11 of 11

This question tests reflection and vertical stretch of a parabola.

‹

\( \begin{array}{l}\text{Describe the transformations applied to the graph of } y = x^2 \text{ to obtain } y = -3x^2.\end{array} \)

Select all correct options:

\( \text{Reflection in x-axis} \) \( \text{Vertical stretch by factor 3} \) \( \text{Translation 4 units up} \) \( \text{No transformation} \)

Check the sign and coefficient for reflection and stretch.

Negative sign reflects the graph, coefficient >1 stretches vertically.
