Math Problem Statement

Describe the transformation of f(x) = x^2 represented by g(x) = (x - 2)^2 - 3. Then identify the graph of each function.

Solution

We are given two functions:

  • f(x)=x2f(x) = x^2
  • g(x)=(x2)23g(x) = (x - 2)^2 - 3

Describing the transformation:

  1. Horizontal Translation: The function g(x)=(x2)23g(x) = (x - 2)^2 - 3 contains (x2)(x - 2) inside the square. This indicates a horizontal translation. Specifically, the graph is shifted 2 units to the right compared to the graph of f(x)=x2f(x) = x^2.

  2. Vertical Translation: The term 3-3 outside the square means the graph is shifted 3 units downward.

Filling in the blanks:

The graph of gg is a translation:

  • 2 units right and
  • 3 units down

of the graph of ff.

Would you like a further explanation or a graph of these transformations? Here are some related questions you could explore:

  1. What other transformations exist beyond translations?
  2. How does the transformation affect the vertex of a parabola?
  3. How would the graph look if the transformation was g(x)=(x+2)2+3g(x) = (x + 2)^2 + 3?
  4. What is the general form for describing transformations of quadratic functions?
  5. Can you describe a reflection transformation for a quadratic function?

Tip: When analyzing transformations, always look for changes to the input (horizontal shifts) and the output (vertical shifts).
