please answer question

Let b E Rm, c E R" constant vectors, A E Rman, Q E Rx two matrices, and the vector variables: x E R" y E Rm Now, let: f(x, y) = cTxt zx]Qx-y(Ax - b) Find the gradient of f: (a) [2 points] with respect to the vector x, that is Vx f(x, y), (b) [2 points] with respect to the vector y, that is Vy f(x, y). Solution: (a) Vxf(x, y) = (a) Vyf(x, y) = Remember to use * for multiplication when entering your
