Final answer:
When we reflect the function f(x) = x² about the y-axis, there are no changes in the equation. The graph of the reflected function would look the same as the original function, just flipped horizontally.
Step-by-step explanation:
When we reflect a function about the y-axis, we change the sign of the x-values. In the case of the function f(x) = x², reflecting it about the y-axis would change it to f(x) = (-x)², which simplifies to f(x) = x².
So, when we reflect the function f(x) = x² about the y-axis, there are no changes in the equation. The graph of the reflected function would look the same as the original function, just flipped horizontally.
