题目:已知函数y=1-x~(1/2)+x+3~(1/2)的最大值为M,最小值为m,则m/M的值为()。A.1/4 B.1/2 C.2~(1/2)/2 D.3~(1/2)/2分析:该题是求根式和的最值问题,灵活利用所学知识,从函数与方程思想、基本不等式、三角换元
Title: It is known that the maximum value of function y = 1-x ~ (1/2) + x + 3 ~ (1/2) is M and the minimum value is m. A.1 / 4 B.1 / 2 C.2 ~ (1/2) / 2 D.3 ~ (1/2) / 2 Analysis: This question is the most value problem of finding roots and summing up the knowledge , From the idea of function and equation, basic inequality, trigonometry
