Math Problem Statement

Determine the equation for the transformed function given the parent function g(x) = |x| and the graph showing the transformation.

Solution

The problem involves identifying the equation of a transformed function based on the graph of a given parent function. The parent function is g(x)=xg(x) = |x|.

Analyzing the Transformation

The graph of g(x)=xg(x) = |x| is a V-shaped graph centered at the origin (0,0) with two arms extending upwards.

In the transformed graph (on the right):

  • The V-shape is upside down, indicating a reflection across the x-axis.
  • The vertex of the V-shape has moved from the origin to the point (2,4)(2, 4), indicating a horizontal shift to the right by 2 units and a vertical shift upwards by 4 units.

Transformations Breakdown

  • Reflection: The reflection across the x-axis changes the function to x-|x|.
  • Horizontal Shift: Moving the graph right by 2 units modifies the function to x2-|x - 2|.
  • Vertical Shift: Moving the graph up by 4 units changes the function to x2+4-|x - 2| + 4.

Conclusion

The transformed function should be:

h(x)=x2+4h(x) = -|x - 2| + 4

Answer Choices:

Given the options:

  • A. h(x)=4x2+4h(x) = -4|x - 2| + 4
  • B. h(x)=x+2+4h(x) = |x + 2| + 4
  • C. h(x)=x2+4h(x) = -|x - 2| + 4
  • D. h(x)=12x+2+4h(x) = \frac{1}{2}|x + 2| + 4

Correct Answer: The correct answer is C: h(x)=x2+4h(x) = -|x - 2| + 4.
