Math Problem Statement

What transformations are needed in order to obtain the graph of h(x) = -|x - 2| from the graph of f(x) = |x|?

Solution

Let's analyze the given function step-by-step.

The base function is f(x)=xf(x) = |x|.

The transformed function is h(x)=x2h(x) = -|x - 2|.

We need to identify the transformations applied to f(x)f(x) to obtain h(x)h(x).

Transformations:

  1. Horizontal shift: The expression x2|x - 2| indicates a horizontal shift to the right by 2 units.

  2. Reflection about the x-axis: The negative sign in front of the absolute value, x2-|x - 2|, reflects the graph over the x-axis, flipping it upside down.

Now, let's match these transformations to the choices provided:

  • A. Horizontal shift: Yes, right by 2 units.
  • E. Reflection about the x-axis: Yes, the negative sign reflects it over the x-axis.

Final Answer:

The transformations needed are:

  • A. Horizontal shift
  • E. Reflection about the x-axis

  1. How would the graph change if the equation was h(x)=x+2h(x) = |x + 2|?
  2. What transformation corresponds to h(x)=2x2h(x) = 2|x - 2|?
  3. How does a vertical shift affect the graph of an absolute value function?
  4. What happens to the graph of f(x)=xf(x) = |x| when reflected over the y-axis?
  5. How does the slope of the arms of the graph change when there's a vertical stretch?

Tip:

When analyzing transformations, always pay attention to signs inside the absolute value and in front of the function, as they indicate shifts and reflections.
