Math Problem Statement

f(x)=|x| is the parent function. Let y= the transformed function. Describe how to obtrain the graph of y (below) from the graph of f(x). Graph both functions to verify your answer. y=|x-3|-3

Solution

The graph above shows both functions:

  • The dashed blue line represents the parent function f(x)=xf(x) = |x|, which is a V-shaped graph with its vertex at (0,0)(0, 0).
  • The red line represents the transformed function y=x33y = |x - 3| - 3, which has been shifted 3 units to the right and 3 units downward, with its vertex at (3,3)(3, -3).

These shifts confirm the transformations described earlier.

Do you have any questions or would you like more details?

Here are 5 related questions to deepen your understanding:

  1. How would the graph change if the function was y=x+33y = |x + 3| - 3?
  2. What happens if we add a coefficient to the absolute value, like y=2x33y = 2|x - 3| - 3?
  3. Can you describe the effect of y=x3+3y = |x - 3| + 3 on the graph?
  4. How would a reflection over the x-axis look in an absolute value function?
  5. What is the effect of a vertical stretch or compression on y=xy = |x|?

Tip: Horizontal shifts are counterintuitive—if you subtract a value from xx, the graph shifts to the right.
