GCSE Maths Practice: graph-transformations

Question 10 of 10

This question tests reflection of a function in the y-axis.

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

Choose one option:

Check for -x inside f(x) to identify reflection in the y-axis.

Negative sign inside the function reflects the graph over the y-axis.
