Math Problem Statement

The graph shows g(x), which is a transformation of f(x) = |x|. Write the function rule for g(x).

Solution

The graph in the image represents a transformation of the function f(x)=xf(x) = |x|, which is the absolute value function.

To determine the function rule for g(x)g(x), let's analyze the transformation:

  1. The vertex of the parent function f(x)=xf(x) = |x| is at the origin (0,0)(0, 0). In the graph of g(x)g(x), the vertex has shifted to (3,2)(-3, 2).

  2. The slope of the lines on both sides of the vertex appears unchanged, meaning that the function has not been vertically stretched or compressed.

This suggests the following transformations:

  • Horizontal shift to the left by 3 units.
  • Vertical shift up by 2 units.

Thus, the function rule for g(x)g(x) is:

g(x)=x+3+2g(x) = |x + 3| + 2

This is the transformed absolute value function where:

  • +3+3 inside the absolute value shifts the graph to the left.
  • +2+2 outside shifts the graph upwards.

Here are 5 related questions:

  1. How do vertical and horizontal shifts affect the graph of a function?
  2. What would happen if we added a coefficient in front of the absolute value, such as 2x+3+22|x + 3| + 2?
  3. How can we use transformations to reflect a graph across the x-axis or y-axis?
  4. What is the general form of a transformed absolute value function?
  5. Can transformations like stretching or compressing occur together with shifts?

Tip: When analyzing graph transformations, always start by identifying the vertex and check for any changes in slope or direction.
