100分+100分4.If y is a function defined as y=√(2x+1),use diffe A function is defined by th equation d(x)=5(x-3)^2+1 英语翻译if the graph of the function y=x^2 is stretched vertical SAT数学思路f(x)=kg(x)+2The function above is defined in terms of y^n+3y'+2y=2x^2+x+1的通解 如果满意再加100分 设5分、2分、1分硬币分别有x、y、z枚x+y+z=100; 2*y/5+x+z=73; 2*y/5+x+z/5=33 if the function f satisfies the equation f(x+y)=f(x)+f(y) fo 100分!验证y=x^2e^x是否为y''-2y'+y=0的解 Write as a function of x, if 0 What is the range of the function y=3x+2 with domain -2≤x≤-1 定积分y=a^x区间[0,1]//细分100份怎么分呀? [急100分]x>0,y>0.且x+y=1,求4/x+1/y的最小值.
