已知函数f(x)=log1/2(x^2+2x+4),则f(-2)与f(-3)的大小关系是
人气:434 ℃ 时间:2020-07-06 09:08:42
解答
f(-2)=log1/2 4
f(-3)=log1/2 7
因为log1/2 x为减函数
所以f(-2)>f(-3)
推荐
已知函数f(x)=log12(x2+2x+4),则f(-2)与f(-3)的大小关系是( ) A.f(-2)>f(-3) B.f(-2)=f(-3) C.f(-2)<f(-3) D.不能确定
若函数f(x)=log1/2(x^2+2x+4),则f(-2009)与f(-2010)的大小关系是?
函数f(x)=log1/2 (x^2-2x+5)
函数f(x)=(log1/2x)^2-log1/2x+5,x
求函数f(x)=-(log1/2x)^2-log1/4x+5在2≤x≤4范围内的最值
