The image of a positive scale function passes through point a (negative 2,3) to write the expression of the function Let the image of a positive scale function pass through point a (negative 2,3) and write the expression of the function. Let the analytic expression of the positive scale function be y = KX Substituting the point (- 2,3) into the analytic expression, we get 3 = - 2K, and the solution is k = - (3 / 2) So the analytic expression of the function is y = - (3 / 2) X
