Answer: D. f(x)-2
Explanation:
Changes insides the parenthesis translate left and right. If it is [+] a number, then it is moving to the left. If it is [-] a number, then it is moving to the right.
Changes outside the parenthesis translate up and down. If it is [+] a number, then it is moving upward. If it is [-] a number, then it is moving downward.
----------------------------------------------------------------------------------------------------
Given
Translate f(x) 2 units downward
Solve
According to the rules, it should be -2 units outside of the parenthesis
Therefore, it should be f(x)-2
