Math Problem Statement
Solution
Let's analyze the problem.
The original function is , and it is shifted 3 units to the left to create a new function .
Key Concept:
When a function is shifted horizontally:
- Left by : Replace with .
- Right by : Replace with .
Thus, for a shift 3 units to the left, we replace with in :
Now, match this with the answer choices:
- A: (Correct)
- B: (Doesn't reflect the shift or match ).
- C: (This is for a shift 3 units to the right, not left).
- D: (No shift, and incorrect constant term).
Final Answer:
The correct choice is A: .
