If x = 1 / 2, the positive scale function y = XK1 (K1 is not equal to 0) is equal to the inverse scale function y = K2 / x, then the ratio of K1 to K2 is? Options: A.4:1 B.2:1 C.1:2 D.1:4 Seeking answers and solving ideas

Choose a
Substituting x = 1 / 2, the positive proportion function y = K1 / 2 (K1 is not equal to 0); the inverse proportion function y = 2k2
So: K1 / 2 = 2k2, so: K1 / K2 = 4:1
