f(xy)=f(x)+f(y),证明f(x/y)=f(x)-f(y)f(xy)=f(x)+f(y),证明f(x/y)=f(x)-f(y)f(xy)=f(x)+f(y),证明f(x/y)=f(x)-f(y)证明令x=x/y,y=y∵f(xy)
f(x+y)=f(x)+f(y)+2xyf(x+y)=f(x)+f(y)+2xyf(x+y)=f(x)+f(y)+2xy游客1:定义在R上的函数f(x)满足f(x+y)=f(x)+f(y)+2xy(x,y∈R)f(1)=2,则f(-3)=?
f(x+y)+f(xy-1)=f(x)f(y)+2f(n)表达式f(x+y)+f(xy-1)=f(x)f(y)+2f(n)表达式f(x+y)+f(xy-1)=f(x)f(y)+2f(n)表达式求什么设x=0,y=0则f(0)+f(-1)=f
f(xy)=f(x)+f(y)的单调性f(xy)=f(x)+f(y)的单调性f(xy)=f(x)+f(y)的单调性令x=y=0f(0)=f(0)+f(0)f(0)=0令y=-xf(x-x)=f(x)+f(-x)0=f(x)+f(-x)f(x
f(xy)=f(x)+f(y),证明f(1/x)=-f(x)f(xy)=f(x)+f(y),证明f(1/x)=-f(x)f(xy)=f(x)+f(y),证明f(1/x)=-f(x)证明:取x=1,y=1,则f(xy)=f(x)+f(y)即f
已知f(xy)=f(x)+f(y),求证f(x/y)=f(x)-f(y)已知f(xy)=f(x)+f(y),求证f(x/y)=f(x)-f(y)已知f(xy)=f(x)+f(y),求证f(x/y)=f(x)-f(y)f(xy)=f(x)+f
f(x/Y)=f(x)-f(y)求证明f(xy)=f(x)+f(y)f(x/Y)=f(x)-f(y)求证明f(xy)=f(x)+f(y)f(x/Y)=f(x)-f(y)求证明f(xy)=f(x)+f(y)因为f(x)=f(xy/y)=f(x
