Final answer:
The expression "f(x - 1)" will cause a horizontal translation (shift) of a function f(x) to the right by 1 unit.
Step-by-step explanation:
The expression "f(x - 1)" represents a horizontal translation (shift) of a function f(x) to the right by 1 unit. It means that every point on the graph of f(x) will be shifted horizontally to the right by 1 unit. Therefore, the correct answer is option D) Horizontal Translation (Shift).
