"F(x,y)=0"F(x,y)=0"F(x,y)=0一个二元函数F(x,y)它的值是0
" F(x,y)=0
" F(x,y)=0
" F(x,y)=0
一个二元函数F(x,y)它的值是0
f(x+y)=f(x)*f(y) x>0 f(x)
恒有f(x+y)=f(x)+f(y),若x>0时,f(x)
f(x+y)=f(x)*f(y) x>0 f(x)
数学题f(X)对一切x y都有f(x+y)=f(x)+f(y)f(X)对一切x y都有f(x+y)=f(x)+f(y)且x>0时,f(x)
已知f(x+y)=f(x)+f(y)+xY(x+y),f’(0)=1.求f(x).
F(x,y)=0
x,y属于R 且f(x)+f(y)=f(x+y)恒成立 当x>0,f(x)
x,y属于R 且f(x)+f(y)=f(x+y)恒成立 当x>0,f(x)
x,y属于R 且f(x)+f(y)=f(x+y)恒成立 当x>0,f(x)
f(x,y)=e^-y,0
导数:f(x+y)=f(x)f(y),且f'(o)=1,求f'(x)f(x+y)=f(x)f(y),且f'(o)=1,求f'(x)f(x+y)=f(x)+f(y)+2xy,且f'(o)存在,求f'(x) f(1+x)=af(x),且f'(0)=b,求f'(1)
f(x+y)+f(x-y)=2f(x)f(y) 求证:f(0)=1
f(x+y)=f(x)-f(y),那么f(-x)=f(0)-f(-x)=-f(-x).2f(-x)=0?
已知:f(x+y)+f(x-y)=2f(x)*f(y),x.y取任何实数且f(0)不等于0,求证:f(x)为偶函数
(X,Y) f(x,y)={12y^2,0
已知函数f(x)满足f(x+y)+f(x-y)=2f(x)×f(y),且f(0)≠0,证明f(x)是偶函数
已知f(0)=1,f(x-y)=f(x)-y(2x-y+1),求f(x)
已知f(x+y)=f(x)乘以f(y),且f(x)不等于0,证明f(x)>0
