Math Problem Statement

List all the transformations on f(x) = |x| that result in the function g(x) = (1/3) |x + 5| - 6.

Solution

We are given the function f(x)=xf(x) = |x| and asked to identify the transformations that result in the function g(x)=13x+56g(x) = \frac{1}{3}|x + 5| - 6.

To analyze this, we will identify the transformations in terms of shifts, stretches, and reflections:

Step-by-Step Transformations:

  1. Horizontal Shift:

    • In g(x)g(x), the term inside the absolute value is x+5x + 5. This corresponds to a horizontal shift to the left by 5 units.
      (If the form is xh|x - h|, the shift is hh, so here it's 5-5).
  2. Vertical Stretch:

    • The coefficient 13\frac{1}{3} outside the absolute value scales the function vertically. Since 13<1\frac{1}{3} < 1, this is a vertical compression by a factor of 3 (the graph is "squished" vertically).
  3. Vertical Shift:

    • The 6-6 at the end represents a vertical shift downward by 6 units.

Summary of Transformations:

  • Horizontal shift left by 5 units.
  • Vertical compression by a factor of 3.
  • Vertical shift downward by 6 units.

Would you like more details or have any further questions?

Here are five related questions:

  1. How would the graph change if the coefficient outside the absolute value was negative?
  2. What transformation would occur if the inside of the absolute value was x5x - 5 instead?
  3. How would the graph change if the 6-6 was positive instead of negative?
  4. Can you describe the effect of multiplying f(x)f(x) by 2 instead of 13\frac{1}{3}?
  5. What happens to the graph if no horizontal shift is applied?

Tip: When dealing with absolute value transformations, always focus on the inside expression for horizontal changes and outside terms for vertical transformations.
