Transcript text: What does the transformation $f(x) \mapsto 4 f(x)$ do to the graph of $f(x)$ ?
shrinks it vertically
shrinks it horizontally
stretches it vertically
stretches it horizontally
Solution
Solution Steps
Step 1: Analyzing Vertical Transformations
Given the transformation \(f(x) \mapsto a f(x)\) with \(a = 4\),
Since \(\lvert a \rvert = \lvert 4 \rvert > 1\), the graph of \(f(x)\) is stretched vertically.
Step 2: Analyzing Horizontal Transformations
Given the transformation \(f(x) \mapsto f(bx)\) with \(b = 1\),
Final Answer:
The transformation \(f(x) \mapsto a f(bx)\) results in:
Since \(\lvert a \rvert = \lvert 4 \rvert > 1\), the graph of \(f(x)\) is stretched vertically.
