Suppose that y = f(x1,x2) = x1X2 for the domain x > 0 and xz>0 and g(y) = ln(y), h(y) = 10y, j(y) = y2, k(y) = e) a) Is the f(x1,x2) a homogeneous function? If so find the degree? b) Is gy) a homothetic function? Is g(y) a homogeneous function in xq and X2 ?If so, what is the degree? c) Is h(y) a homothetic function? Is h(y) a homogeneous function in xy and X2 ?If so, what is the degree? d) Is (y) a homothetic function? Is j(y) a homogeneous function in x and x2?If so, what is the degree? e) Is k(y) a homothetic function? Is k(y) a homogeneous function in x and x2?If so, what is the degree
