If the function defined on R, y = f (x), and the image of y = f (x + 2) is symmetric with respect to x = 0, then the symmetry axis of the image of the function y = f (x)

If the function defined on R, y = f (x), and the image of y = f (x + 2) is symmetric with respect to x = 0, then the symmetry axis of the image of the function y = f (x)

The image of y = f (x + 2) is symmetric with respect to x = 0, which is an even function,
You can draw any curve that is symmetric about the Y axis, for example, y = x ^ 2,
Let y = f (x + 2),
If we want to change f (x + 2) into f (x), as long as f (X-2 + 2) equals f (x),
So as long as the image is shifted 2 units to the right, the symmetry axis is x = 2
