    functionssssssss

    we're reviewing for the final and i don't remember how to do this i have a feeling it's very simple, and i'm just thinking too hard. any help please?

    if f(x) = ax/a+x where a is a constant value and x cannot equal a, find and simplify:

    a) f(a)

    b) f(1-a)

    c) f(1/1-a)

    a) f(a)

    b) f(1-a)

    c) f(1/1-a)
    f(z) = \frac{ax}{a+x}

    Plug & Chug...

    Here is c) f(\frac{1}{1-a}) = \frac{a\frac{1}{1-a}}{a+\frac{1}{1-a}}
    f(\frac{1}{1-a}) = \frac{a(1-a)}{(1-a)(a-a^2+1)}
