solve question 3 . find Homothetic functions?. and also draw a graph for each ..thanks

Q 3: Which of the following functions are homothetic functions? i) Y = exixze*1x] ii) Y = 2logX1 + 3logX2 iii) Y = X3X5 + 3X}X2 + 6X,X3 +9 iv) Y = XXX2 + X1X3 V) Y = XX2+1 vi) Y = XX +X1X2 vii) Y = log(X1/X2) vili) Y = X1X2 + 5 ix) Y = InX, + InX2 x) Y = 3(X,1x22+ 2x3) + log (X,'X22 + 2x3) + 1005 xi) Y = (XX2)2 xii) Y = XXX2 + 1 xiii) InY = InA+
