Q. What does the transformation f(x)↦f(x−4) do to the graph of f(x)?Choices:(A) translates it 4 units right(B) translates it 4 units down(C) translates it 4 units left(D) translates it 4 units up
Given Transformation: We are given the transformation f(x)↦f(x−4). We need to determine how this transformation affects the graph of the original function f(x).
Recognition of Horizontal Shift: Recognize that the transformation involves the input variable x. The transformation f(x)↦f(x−4) indicates a horizontal shift, as it changes the x-value at which a particular y-value of the function is obtained.
Direction of Horizontal Shift: Determine the direction of the horizontal shift. In the transformation f(x)↦f(x−4), the x-value is being reduced by 4 before being input into the function. This means that every point on the graph of f(x) will be shifted to the right by 4 units to compensate for this reduction.
Confirmation of Vertical Shift: Confirm that the transformation does not involve any vertical shift, as there is no addition or subtraction outside the function f(x). Therefore, there is no translation up or down.
