Math Problem Statement

Use the graph of y = f(x) to graph the function g(x) = (1/2) f(x - 2). Choose the correct graph of g.

Solution

Let's break down the problem based on the graph and the function given:

Problem Details:

  • You are asked to use the graph of y=f(x)y = f(x) (on the left side) to graph the function g(x)=12f(x2)g(x) = \frac{1}{2} f(x - 2).
  • The operation g(x)=12f(x2)g(x) = \frac{1}{2} f(x - 2) applies two transformations to the function f(x)f(x):
    1. Horizontal Shift: x2x - 2 shifts the graph 2 units to the right.
    2. Vertical Compression: 12\frac{1}{2} compresses the graph vertically by a factor of 2 (all y-values are halved).

Applying Transformations:

  1. Horizontal Shift: Move the entire graph of f(x)f(x) 2 units to the right.
  2. Vertical Compression: For each y-value of the shifted graph, multiply it by 12\frac{1}{2}.

Observing the Graphs:

From the provided options (A, B, C, D), the graph that correctly applies both transformations is B. It shows:

  • A shift 2 units to the right.
  • All y-values compressed to half of their original values.

Answer: The correct graph is B.

Would you like further clarification on the transformations or the solution process?

Here are five follow-up questions for more practice:

  1. How would the graph of g(x)=2f(x+1)g(x) = 2f(x + 1) transform the graph of f(x)f(x)?
  2. What effect does multiplying a function by a negative constant have on its graph?
  3. How would g(x)=13f(x+3)g(x) = \frac{1}{3}f(x + 3) change the graph of f(x)f(x)?
  4. What happens if you add a constant to f(x)f(x), like g(x)=f(x)+3g(x) = f(x) + 3?
  5. Can you describe the transformation for g(x)=f(x1)g(x) = -f(x - 1)?

Tip: Always apply horizontal shifts before vertical stretches or compressions when analyzing transformations.
