Solution

To find the function rule for g(x) g(x) based on the transformation of f(x)=x f(x) = |x| , we first need to analyze how the graph of g(x) g(x) has been modified from f(x) f(x) .

Step 1: Identify Transformations

  1. Vertical Shifts: Determine if the graph is moved up or down.
  2. Horizontal Shifts: Determine if the graph is moved left or right.
  3. Reflections: Check if the graph has been reflected over the x-axis or y-axis.
  4. Stretches/Compressions: Analyze if the graph has been stretched or compressed vertically or horizontally.

Step 2: Write the Function Rule

Based on the transformations identified, we can express g(x) g(x) as a function of f(x) f(x) .

  1. Shift Down: If the graph of g(x) g(x) is shifted down by a certain amount, subtract that amount from f(x) f(x) .
  2. Horizontal Shift: If the graph shifts right by h h , replace x x with xh x - h , or shift left by h h with x+h x + h .
  3. Reflections: If the graph is reflected across the x-axis, multiply f(x) f(x) by -1.

Step 3: Analyze the Specific Graph

Without the actual graph to reference, the general rule can only be discussed. Assuming specific transformations could look something like this:

  • If g(x)=x23 g(x) = |x - 2| - 3 , this means the graph of f(x) f(x) was shifted right by 2 and down by 3.

Step 4: Finalize the Function Rule

Once you confirm the transformations by analyzing the visual representation of the graph:

Final Answer

Write g(x) g(x) in the appropriate form based on the transformations you've noted. For example, g(x)=xh+k g(x) = |x - h| + k , where h h and k k are the horizontal and vertical shifts respectively.
