Final answer:
The graph of f(x) = x : A) shifts 3 units to the right and 9 units down when changed to f(x) = (x - 3)^²- 9. Hence, A) is correct.
Step-by-step explanation:
The function f(x) = (x - 3)² - 9 represents a transformation of the graph of f(x) = x. Let's break down the effect of each transformation:
- The expression (x - 3)² shifts the graph 3 units to the right.
- The expression -9 shifts the graph 9 units down.
Therefore, the correct answer is A. The graph shifts 3 units to the right and 9 units down.
