If the function f (x) has f (a + x) = - f (A-X) for all real numbers in the domain of definition, then the image f (x) of the function is a centrosymmetric graph whose center of symmetry is

If the function f (x) has f (a + x) = - f (A-X) for all real numbers in the domain of definition, then the image f (x) of the function is a centrosymmetric graph whose center of symmetry is

Center of symmetry (a, 0), if you don't consider that symbol, you can judge that x = a is the axis of symmetry, but if there are more symbols, it means the image is flipped, so it becomes a centrosymmetric figure. Question: how does the center of symmetry (a, 0) come out? Answer: the intersection of the axis of symmetry and the X axis question: why is the axis of symmetry a... answer: draw a picture, you can understand it slowly
