Differentiate:

f(x) = 2x-(x^2+1)^7 / 3

the answer choices are
1) f'(x) = 2-x / 3(x^2+1)^6
2) f'(x) = 2/3 - 14/3 x(x^2+1)^6
3) None of the above

so the answer would number 1 correct?

  1. looks pretty straightforward to me

    y = 2x - (1/3)(x^2 + 1)^7
    dy/dx = 2 - (7/3)(x^2 + 1)^6 (2x)
    = 2 - (14/3)x(x^2+1)^6

    neither of their answers are correct

  2. In google type: calc101

    When you see list of results click on:

    Calc101com Automatic Calculus,Linear Algebra and Polynomials

    When page be open clik option: derivatives

    When this page be open in rectacangle type:

    2x-(x^2+1)^7/3

    and click options DO IT

    You will see solution step-by-step

    By the way on this site you can practice any kind of derivation.
