SUMMARY

The discussion focuses on rewriting the function g(x) = 2x - |3x - 2| as a piecewise function, resulting in G(x) = {-x + 2, x ≥ 2/3; 5x - 2, x < 2/3. Additionally, it addresses the domain and equation of f(g(x)) where g(x) = √(x + 1) and f(x) = 3/x, highlighting that the domain of f(x) excludes 0 and the domain of g(x) is x ≥ -1. The range of the piecewise function P(x) is also discussed, with specific intervals defined for each piece.

PREREQUISITES
  • Understanding of piecewise functions
  • Knowledge of absolute value functions
  • Familiarity with domain and range concepts
  • Basic calculus principles, particularly function composition
NEXT STEPS
  • Study piecewise function notation and applications
  • Learn about absolute value transformations in functions
  • Explore domain and range determination for composite functions
  • Investigate function composition techniques and their implications
USEFUL FOR

Students in calculus or algebra courses, mathematics educators, and anyone looking to deepen their understanding of piecewise functions and function composition.

Homework Statement


1. Rewrite as piecewise: g(x) = 2x - |3x-2|

2. Give domain and equation represented by f(g(x)) when g(x) = √(x+1) and f(x) = 3/x

3. Give range of P(x) = {2x-1, x >/= 1
{x^2 + 1, -1 </= x < 1
{√|x|, x<-1

thanks in advance

What are you thoughts on numbers 2 and 3?

For number 2, note that the domain of f(x) is the set of all points but 0, since you're not allowed to divide by 0. The domain of g(x) is all x>=-1 (or else you'd be taking the square root of a negative number, which is not allowed, either). How do you combine this information to determine the domain of f(g(x))?
