Math Problem Statement

Use transformations of f(x) = x^2 to graph the following function h(x) = (x - 5)^2 - 4. Select all the transformations that are needed to graph the given function.

Solution

The given function is:

h(x)=(x5)24h(x) = (x - 5)^2 - 4

This function is a transformation of the parent function f(x)=x2f(x) = x^2, a standard quadratic function. Let's break down the transformations:

  1. Horizontal Shift: (x5)2(x - 5)^2 means that the graph of f(x)=x2f(x) = x^2 is shifted 5 units to the right.
  2. Vertical Shift: The constant 4-4 indicates that the graph is shifted 4 units down.
  3. No Reflection: Since the squared term is positive, there is no reflection over the x-axis or y-axis.
  4. No Stretch or Shrink: The coefficient of the squared term is 1, meaning there is no vertical or horizontal stretch or shrink.

Based on this analysis, the correct transformations are:

  • DD: Shift the graph 5 units to the right.
  • II: Shift the graph 4 units down.

The correct answer choices are:

  • DD
  • II

Would you like further explanation or details? Here are five questions you can consider next:

  1. How would the graph look if we reflected it over the x-axis?
  2. What would happen if the graph were stretched vertically by a factor of 2?
  3. Can you describe the transformation if the function was h(x)=(x+3)2+2h(x) = -(x + 3)^2 + 2?
  4. How does the horizontal shift affect the vertex of the parabola?
  5. How would a horizontal shrink by a factor of 4 modify the graph?

Tip: When analyzing transformations of functions, always look at how the terms inside parentheses and outside constants affect the graph's shape, position, and orientation!
