    Precalculus Problem

    If anyone could help me out in this, it would be greatly appreciated

    1. for the given linear function compute the quotient
    [f(x+h) -f(x)]/ h

    where h is constant.

    f(x) = -9x^2 + 12


    this is the exact wording, so if it seems confusing, i dont know how else to put it...thanks....

    You know that f(x+h)=-9(x+h)^2+12, now substitute and reduce carefully.
