Math Problem Statement

The given figure shows a transformation of the graph of f(x) = |x|. Write the equation for the transformed graph.

Solution

The problem asks for the equation of a transformed graph based on the original graph f(x)=xf(x) = |x|. The graph appears to have undergone a series of transformations, including scaling and possible reflections.

From the uploaded image, we observe the following:

  1. The original f(x)=xf(x) = |x| graph has its vertex at the origin (0,0)(0, 0) and is symmetric about the y-axis.
  2. In the transformed graph:
    • The vertex remains at the origin (0,0)(0, 0), indicating no horizontal or vertical shifts.
    • The slopes of the two arms of the "V" shape are different from the original f(x)=xf(x) = |x|. Specifically:
      • The right arm has a slope of 3.
      • The left arm has a slope of 3-3.

This transformation is a vertical stretch of the graph f(x)=xf(x) = |x| by a factor of 3.

Final Answer:

The equation for the transformed graph is: y=3x.y = 3|x|.

Tip:

When identifying transformations, always analyze the vertex, slopes, and symmetry of the graph to match the transformations applied to the original equation.
