GCSE Maths Practice: graph-transformations

Question 4 of 10

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

‹ ›

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

Select all correct options:

\( \text{Graph is unchanged} \) \( \text{Graph is modified} \) \( \text{Reflection in y-axis} \) \( \text{No transformation} \)

Check for -x inside the function to identify reflection in the y-axis.

Replacing x with -x reflects the graph over the y-axis, reversing all x-values.
