As shown in the figure, it is known that the image of inverse scale function y = K1 / 2x and the image of linear function y = k2x + B intersect at two points a and B, a (2, n), B (- 1, - 2) 2) When what is the value of X, the value of the first-order function is greater than that of the inverse proportion function? 3) find the area of △ AOB
