Math Problem Statement

Sketch the graph of the quadratic function f(x) = (x - 2)^2 - 4 by using translations (vertical or horizontal shifts). Compare the graph to the graph of f(x) = x^2.

Solution

The problem on your screen involves sketching the graph of the quadratic function f(x)=(x2)24f(x) = (x - 2)^2 - 4 by using translations (shifts) and comparing it to the graph of f(x)=x2f(x) = x^2.

Let’s break down the solution step by step:

  1. Standard Quadratic Function: The basic graph of f(x)=x2f(x) = x^2 is a parabola that opens upwards with its vertex at (0,0)(0, 0).

  2. Transformations: The given function is f(x)=(x2)24f(x) = (x - 2)^2 - 4. This involves two transformations:

    • The term (x2)(x - 2) represents a horizontal shift 2 units to the right.
    • The term 4-4 represents a vertical shift 4 units downward.
  3. Final Graph Description: So, the graph of f(x)=(x2)24f(x) = (x - 2)^2 - 4 is a parabola identical to the graph of f(x)=x2f(x) = x^2, but it is shifted 2 units to the right and 4 units downward.

To fill in the blanks:

  • The graph is shifted 2 units to the right.
  • The graph is shifted 4 units down.

Here are 5 follow-up questions that expand on this:

  1. What is the general form of a quadratic function that involves horizontal and vertical shifts?
  2. How would the graph change if the quadratic function included a coefficient, like f(x)=2(x2)24f(x) = 2(x - 2)^2 - 4?
  3. What is the vertex of the transformed parabola f(x)=(x2)24f(x) = (x - 2)^2 - 4?
  4. Can you describe how to determine the direction in which a parabola opens?
  5. What other types of transformations could be applied to quadratic functions?

Tip: When graphing functions, always pay attention to horizontal and vertical shifts as they dictate the new position of the vertex of a parabola.
