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 from the options provided.

Solution

The problem is asking to graph the function g(x)=12f(x2)g(x) = \frac{1}{2} f(x - 2) using the provided graph of y=f(x)y = f(x).

Here’s how we approach it:

  1. Horizontal Shift: The expression f(x2)f(x - 2) indicates a horizontal shift. Specifically, the graph of f(x)f(x) is shifted 2 units to the right.

  2. Vertical Compression: The coefficient 12\frac{1}{2} outside the function means the graph undergoes a vertical compression by a factor of 2. This makes the graph half as tall as the original.

Steps to transform the graph:

  • Shift the graph 2 units to the right.
  • Vertically compress the graph, halving the height of each point.

Now, analyzing the options:

  • Option A shows a vertically compressed graph, but it is not shifted.
  • Option B shows the correct shift of 2 units right and a correct vertical compression.
  • Option C does not show the correct shift or compression.
  • Option D shows a shift, but it is not vertically compressed correctly.

Thus, Option B is the correct graph of g(x)g(x).

Here are 5 related questions to expand on the concept:

  1. What is the effect of a horizontal shift on any function?
  2. How does vertical compression/stretching affect the graph of a function?
  3. What happens if you apply a negative coefficient to a function (e.g., f(x)-f(x))?
  4. How would you graph f(x+2)f(x + 2) instead of f(x2)f(x - 2)?
  5. How can you describe the transformation of f(x)f(x) using a table of values?

Tip: Always apply horizontal shifts before vertical transformations when working with composite transformations.
