The correct answer is D) f(-2x).
When a function is reflected across the y-axis, the x-values change signs. In other words, if the original function is f(x), the reflected function is f(-x).
In option D) f(-2x), the function is being reflected across the y-axis as the x-values are multiplied by -1.
