Math Problem Statement

Given the parent function f(x) = x^2, what is the new equation if the function is translated 4 units to the right and 3 units down?

Solution

The problem asks about transforming a function based on a translation. Specifically, for Question 9:

The given parent function is f(x)=(x)2f(x) = (x)^2, and the task is to translate the function 4 units to the right and 3 units down.

Translating a Function:

  1. Translation to the right: To translate the graph of a function f(x)f(x) to the right by hh units, you replace xx with (xh)(x - h). In this case, h=4h = 4, so you replace xx with (x4)(x - 4).

  2. Translation downward: To translate a function downward by kk units, you subtract kk from the function. Here, k=3k = 3, so you subtract 3 from the function.

New Equation:

Combining these transformations, the new equation becomes: f(x)=(x4)23f(x) = (x - 4)^2 - 3

Let me know if you'd like more details on how transformations work!

Related Questions:

  1. What happens to the graph if the function is translated 4 units to the left instead of the right?
  2. How does translating a function upward by 3 units affect the equation?
  3. What are the effects of reflecting a function about the x-axis?
  4. Can you describe the difference between vertical and horizontal stretches of a quadratic function?
  5. How does combining shifts and stretches impact the shape of the graph?

Tip:

When working with transformations, always focus on how each shift or stretch modifies the xx and yy coordinates of key points.
