Math Problem Statement

Describe the transformation of f(x) = x^2 represented by g(x) = (x - 4)^2. Identify the graph of each function and explain the translation of g in relation to f.

Solution

The problem involves analyzing the transformation of the function f(x)=x2f(x) = x^2 to the function g(x)=(x4)2g(x) = (x - 4)^2.

Step-by-Step Solution:

  1. Transformation Analysis:

    • The function g(x)=(x4)2g(x) = (x - 4)^2 represents a horizontal translation of f(x)=x2f(x) = x^2.
    • Specifically, the expression (x4)(x - 4) indicates a shift 4 units to the right of the graph of f(x)f(x).
  2. Translation Direction:

    • Therefore, g(x)g(x) is a translation of f(x)f(x) by 4 units to the right.
  3. Graph Identification:

    • Looking at the provided graphs:
      • In the correct graph, the red parabola (representing g(x)g(x)) should be shifted to the right of the blue parabola (representing f(x)f(x)).
      • In this case, the second graph on the right column correctly shows g(x)g(x) translated 4 units to the right of f(x)f(x).

Answer:

  • The transformation is a horizontal shift 4 units to the right.
  • The graph of g(x)g(x) is correctly identified as the second one in the right column where the red parabola is to the right of the blue one.

Here are 5 related questions for deeper understanding:

  1. What would the transformation g(x)=(x+4)2g(x) = (x + 4)^2 look like on the graph of f(x)=x2f(x) = x^2?
  2. How would you describe a vertical shift transformation for f(x)f(x)?
  3. How does the function g(x)=x2g(x) = -x^2 transform the graph of f(x)=x2f(x) = x^2?
  4. What effect does a horizontal compression have on the graph of f(x)f(x)?
  5. How would the function g(x)=(x4)2+3g(x) = (x - 4)^2 + 3 affect the graph of f(x)=x2f(x) = x^2?

Tip: For horizontal transformations, (xh)(x - h) shifts the graph right by hh units, while (x+h)(x + h) shifts it left by hh units.
