Math Problem Statement

The graph shows g(x), which is a translation of f(x)=x2. Write the function rule for g(x).

Solution

To write the function rule for g(x)g(x), we need to determine how the graph of f(x)=x2f(x) = x^2 has been translated.

Steps to Identify the Transformation:

  1. Vertical Shift: If the graph is moved up by kk units, the new function is g(x)=x2+kg(x) = x^2 + k. If moved down, it is g(x)=x2kg(x) = x^2 - k.
  2. Horizontal Shift: If the graph is moved right by hh units, the function becomes g(x)=(xh)2g(x) = (x - h)^2. If moved left, it becomes g(x)=(x+h)2g(x) = (x + h)^2.
  3. Reflections & Stretches: If the graph is flipped downward, the function has a negative sign: g(x)=x2g(x) = -x^2. If it is stretched or compressed, a coefficient aa is added: g(x)=a(xh)2+kg(x) = a(x - h)^2 + k.

Solution:

Please upload the graph so I can analyze the specific transformation and provide the exact function rule for g(x)g(x).

Would you like an example of how different translations affect a function?
Here are five related questions:

  1. How does shifting a function horizontally affect its equation?
  2. What does the coefficient aa do in g(x)=a(xh)2+kg(x) = a(x - h)^2 + k?
  3. How do you reflect a function across the x-axis or y-axis?
  4. What is the vertex form of a quadratic function?
  5. How can you determine the equation of a parabola given its vertex?

Tip: The vertex of a quadratic function in the form g(x)=a(xh)2+kg(x) = a(x - h)^2 + k is at (h,k)(h, k).
