Math Problem Statement

Describe the transformation of f(x) = x^2 represented by g(x) = (x - 2)^2 - 4. Then identify the graph of each function.

Solution

We are given two functions:

  • f(x)=x2f(x) = x^2
  • g(x)=(x2)24g(x) = (x - 2)^2 - 4

The transformation from f(x)f(x) to g(x)g(x) involves two shifts:

  1. Horizontal shift: The expression (x2)(x - 2) indicates a shift to the right by 2 units.
  2. Vertical shift: The constant term 4-4 outside the squared term indicates a shift downward by 4 units.

Thus, the graph of g(x)g(x) is a translation of the graph of f(x)=x2f(x) = x^2 2 units to the right and 4 units downward.

Now, for the missing terms in the statement:

"The graph of gg is a translation 2 units to the right and 4 units down of the graph of ff."

Do you need further explanation or clarification?


Here are 5 questions to deepen your understanding:

  1. What is the general form of a quadratic transformation?
  2. How would the graph change if the transformation were g(x)=(x+2)24g(x) = (x + 2)^2 - 4?
  3. Can you identify other transformations that affect the shape of the graph, like stretching or reflection?
  4. How do translations impact the vertex of a parabola?
  5. What are the key features (vertex, axis of symmetry) of the graph of g(x)g(x)?

Tip: When identifying transformations, always look for horizontal and vertical shifts, stretches, and reflections by examining the equation's structure.
