I am having some trouble with this question. Thank you so much in advance for your help

Suppose that the vector field F = < y^2, 3 x y >. C is the curve that starts at (0,0) and goes to (2,8) along the cubic y = x^3, then returns to (0,0) along the line y = 4x.

a) Sketch C

b) Using Green's Theorem, findc y^2 dx + 3 x y dy
