    Help With Antiderivative

    If f is the function defined by f(x)=cuberoot(x^2+4x) and g is the antiderivative of f such that g(5)=7, then g(1)=

    A)-3.882
    B)-3.557
    C)1.710
    D) 3.557
    E) 3.882

    I really have no idea how to take than antiderivative, I don't even know if its necessary to take it

    looks like a calculator active problem to me.

    g(5) - g(1) = \int_1^5 f(x) \, dx

    g(1) = g(5) - \int_1^5 f(x) \, dx

    use the fnint feature of your calculator.
