If the point g(-4,6) was moved horizontally 4 units to the left which of the following is the correct mapping to define the translation

D

Step-by-step explanation:

A shift of 4 units horizontally left means subtract 4 from the x- coordinate, leaving the y- coordinate unchanged.

A shift of 4 units horizontally right means add 4 to the x- coordinate while leaving the y- coordinate unchanged.

Hence translation rule is

(x, y) → (x - 4, y), that is

(- 4, 6) → (- 4 - 4, 6) → (- 8, 6)

ab will be equal to

not sure but it may be b, as i said i'm not sure.
