Math Problem Statement

Given the function f(x) = |x|, write the function if f(x) was translated left 1 unit and up 2 units.

Solution

The question in the image asks to find the new function g(x)g(x) after translating the function f(x)=xf(x) = |x| left 1 unit and up 2 units.

For translations:

  • A translation left by 1 unit modifies the function inside the absolute value by adding 1: f(x+1)f(x + 1).
  • A translation up by 2 units adds 2 to the entire function: f(x+1)+2f(x + 1) + 2.

Therefore, the new function g(x)g(x) becomes: g(x)=x+1+2g(x) = |x + 1| + 2

The correct answer is: g(x)=x+1+2\boxed{g(x) = |x + 1| + 2}

Would you like more details on this? Here are five related questions to expand on this topic:

  1. What happens to the graph of f(x)=xf(x) = |x| when translated down 3 units?
  2. How does translating right by 2 units affect f(x)=xf(x) = |x|?
  3. What is the general form of a function translated left by hh units and up by kk units?
  4. How do reflections affect the absolute value function f(x)=xf(x) = |x|?
  5. Can horizontal and vertical stretches or compressions be combined with translations?

Tip: Translations inside the absolute value modify the xx-axis movements, while changes outside affect vertical movements!
