    Calculus differentiation
    Using the following table, which of the following is NOT an approximation of (dy/dx) at x=2?


    x: -6 -5 -4 -3 -2 -1 0
    f(x):25 14 6 1 -3 -5 0

    I think your question here may be incomplete. It looks like the question has to do with secant slopes being used to approximate the tangent slope at x = 2. Either that, or making an inference about the dy/dx value based on given f(x) values on the stated domain. IF this is a multiple choice question, you left out the answer choices.
