Homework Help: Algebra Inverse Function Problem

  1. Jul 26, 2011 #1
    1. The problem statement, all variables and given/known data
    f(x)=(x-3)^2 -1 for x ≥3

    2. Relevant equations

    3. The attempt at a solution
    I am having difficulty grasping the concept of changing the greater than or equal to part of the equation above to it's inverse form. If for x it says x≥3 then how would that statement be relevant to finding the inverse of the function. In other words, I need clarification as to how that specific aspect of the equation changes in inverse form.

    Well, what does the condition x≥3 mean for the equation f(x)=(x-3)^2 -1 ?
  4. Jul 26, 2011 #3
    That the domain is limited and does not include all real numbers for the function. I guess it sets a domain limit?
