Multivariable Calculus Image Provided Let C be an oriented curve in R3; f = f(x,y,z) a function and F a vector field. Which of the following is true? The Answer Key (without solution) is telling me the answer is D.... I really beg you.. could you please explain the reasons behind why your answer(s) are true and others are false? While exam is soon, I am really having hard time understanding the concept--fundamentals behind it. I will promise to sincerely...

If f(x, y) is continuous in an open rectangle R = (a, b) x (c, d) in the xy-plane that contains the point (xo, Yo), then there exists a solution y(x) to the initial-value problem dy = f(x, y), y(xo) = yo, dx that is defined in an open interval I = (a, b) containing xo. In addition, if the partial derivative Ofjay is continuous in R, then the solution y(x) of the given equation is unique. For the initial-value...
