Math Problem Statement

Find g(x), where g(x) is the translation 5 units left and 5 units up of f(x)=|x|. Write your answer in the form a|x–h|+k, where a, h, and k are integers. g(x)=

Solution

To find the translation of f(x)=xf(x) = |x| that moves 5 units to the left and 5 units up, we need to apply transformations accordingly:

  1. Left Translation by 5 Units: Shifting left means we add 5 to xx. So, we replace xx with x+5x + 5 in the function.

    • This gives x+5|x + 5|.
  2. Up Translation by 5 Units: Shifting up means we add 5 to the entire function.

    • This gives x+5+5|x + 5| + 5.

Thus, the translated function g(x)g(x) is: g(x)=x+5+5g(x) = |x + 5| + 5

This is already in the form axh+ka|x - h| + k, where:

  • a=1a = 1,
  • h=5h = -5,
  • k=5k = 5.

Would you like more details or have any questions?

Here are five related questions:

  1. How do different translations (left, right, up, down) affect the graph of an absolute value function?
  2. What would happen if we reflected the graph of f(x)=xf(x) = |x| across the x-axis?
  3. How can we identify the vertex of a translated absolute value function?
  4. How do we describe horizontal and vertical stretches or compressions of x|x|?
  5. What effect does changing the value of aa have on the graph of axa|x|?

Tip: Translating a function left or right involves changing the input (inside the absolute value), while translating up or down affects the output (outside the absolute value).
