Math Problem Statement

Graph the function f(x) = x^2 - 2 and describe how it was translated from f(x) = x^2.

Solution

The question asks to graph the function f(x)=x22f(x) = x^2 - 2 and describe how it was translated from the function f(x)=x2f(x) = x^2.

Translation description:

The base function is f(x)=x2f(x) = x^2, which is a standard parabola with its vertex at the origin (0, 0). The function f(x)=x22f(x) = x^2 - 2 can be seen as a vertical translation of f(x)=x2f(x) = x^2. The "-2" means the graph is shifted downward by 2 units. Therefore, the vertex of the parabola moves from (0, 0) to (0, -2).

In summary:

  • Vertical Translation: The graph is shifted 2 units downward.

Would you like further details or help with graphing it? Here are five questions to expand on this topic:

  1. How do horizontal translations affect the graph of a quadratic function?
  2. What happens to the graph of f(x)=x2f(x) = x^2 when a coefficient is added to x2x^2 (e.g., f(x)=2x2f(x) = 2x^2)?
  3. How does the graph change if the function were f(x)=(x2)2f(x) = (x - 2)^2?
  4. Can you explain how to determine the vertex of a quadratic function?
  5. What effect does a negative sign before the x2x^2 term have on the shape of the parabola?

Tip: When graphing quadratic functions, always start by identifying the vertex and direction of the parabola (whether it opens up or down).
