Solution
Solution Steps
Step 1: Identify the transformations in the function
The original function is \( f(x) = x^2 \). The transformed function is \( 4f(x+3) = 4(x+3)^2 \).
Step 2: Analyze the horizontal transformation
The term \( (x+3) \) inside the function indicates a horizontal shift. Specifically, \( f(x+3) \) represents a shift of the graph of \( f(x) \) to the left by 3 units.
Step 3: Analyze the vertical transformation
The coefficient \( 4 \) outside the function \( f(x+3) \) indicates a vertical stretch. Specifically, multiplying the function by 4 stretches the graph vertically by a factor of 4.
Step 4: Combine the transformations
The function \( 4(x+3)^2 \) undergoes a horizontal shift to the left by 3 units and a vertical stretch by a factor of 4. Therefore, the correct transformation is "translated to the left and stretched vertically."
Final Answer
The correct answer is "translated to the left and stretched vertically."
