GCSE Maths Practice: graph-transformations

Question 3 of 10

This question tests horizontal stretch of a function.

‹ ›

\( \begin{array}{l}\text{Describe the transformation from } y = f(x) \\\text{to } y = f(0.5x).\end{array} \)

Choose one option:

\( \text{Stretch in x-direction by scale factor 1/3} \) \( \text{Stretch in x-direction by scale factor 2} \) \( \text{Translation 3 units down} \)

Check the coefficient of x inside the function to identify horizontal stretch.

Multiplying x inside the function by a fraction less than 1 stretches the graph horizontally.
