Hi, I was doing some review and I'm having trouble with this practice question, I was wondering if you'd be able to help me out with it, please. Thank you in advance.

Consider the two functions f and g defined as: f(x, y) = (2vx+ vy)/(x+y) where > > 0 and y > 0 and g(x, y) = i. Is f(a, y) homogeneous and, if so, of what degree? ii. Is g(x, y) homogeneous and, if so, of what degree? iii. Suppose that ha,y) is a function that is homogeneous of degree o. Determine if the function (h(ry))is homoge- neous and. if so, of what degree
