Y=log(2)(x)-x/2+2零点个数为?

函数y=x^2-log(1/2)x的零点个数大神们帮帮忙函数y=x^2-log(1/2)x的零点个数 谁来解 Y=log(2)(x)-x/2+2零点个数为? y=x^2-log(1/2)x的零点个数 函数f(x)=2^x|log下0.5上x|-1的零点个数为 2log(m)y-log(m)x-log(m)z 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 若函数y=3cos(π/2x)—log1/2x的零点的个数若函数y=3cos(π/2x)—log（1/2）x的零点的个数 log 9 X/Y=1/2(log 3 X - log 3 Y) log 9 X/Y=1/4 3log 3 X =2log 3 Y find X and Y 求函数f(x)=log2x-x+2的零点个数求函数f(x)=log(2)x-x+2的零点个数， 已知函数f(x)=x^2 +3(m+1)x + n的零点是1和2,求函数y=log底数n (x^2 +mx-n)的零点. log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,求每步详...log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解, [log(4)(2x)][log(2x)(3y)][log(3y)(z)]=log(8x)[(8x)]^2,则z=? 怎么画出y=log|x+2|和y=log|x|的图像 确定函数f(x)=log以1/2为底的x+x-4的零点个数 已知a是f(x)=2的x次方-log底数1/3真数x的零点,若0 y=log(-x^2+2x+9)值域 y=2x^2-2^x的零点个数 求零点 y=x^2-5x+4
