Functions change of rate

  1. Feb 12, 2008 #1
    1. The problem statement, all variables and given/known data
    a)find the average rate of change of f from 1 to x:

    f(x) - f(1)
    ----------- , x ≠1
    x-1

    given f(x) = x^2 - 2 x
    2. Relevant equations



    3. The attempt at a solution

    RoC(rate of change)=
    (x^2 - 2x) - [(1)^2 -2(1)]
    -------------------------------
    (x-1)
    2. By simplifying the equation,
    RoC = [(x^2 -2x+1)]/(x-1)


    Can anyone check to see if this is right?

    You can further simplify the fraction [(x^2 -2x+1)]/(x-1).
