If the image of function y = f (x + 2) passes through the point (- 1,3), then the image of function f (x) must pass through the point with respect to the image of y-axis symmetry A(1,-3) B(-1,3) C(-3,-3) D(-3,3)

If the image of function y = f (x + 2) passes through the point (- 1,3), then the image of function f (x) must pass through the point with respect to the image of y-axis symmetry A(1,-3) B(-1,3) C(-3,-3) D(-3,3)

B y = f (x + 2) passes through the point (- 1,3). According to the characteristics of image translation, left plus right minus indicates that f (x + 2) is obtained by two units of F (x) translation to the left, then f (x) passes through the point (- 1,3) when it is symmetrical about the Y axis
