f(x)=x-2/(x^2-3x+2) 求间断点及其类型 并说明为什么.、

f(x)=x^2+x (x f(X)=f(X+2)(x f(x+2)>=f(x)+2,f(x+3) 已知f(x)满足2f(x)+f(1/x)=3x,求f(x) F(X)满足F(x)+2f(x分之1)=3X,求f(x) 已知f(x)满足2f(x)+f(1/x)=3x,求f(x)? 已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x) 已知f(x)满足f(x)+2f(1/x)=3x,求f(x) , f(x-1)=x^2-2x+3(x f(x)=x^2+2x-3(x f(x)=(x-1)(x-2).(x-3)求导 f(x)=5x+3 f(x)=5x f(x)=x+2x+1 f(x)=5x+3 f(x)=5x f(x)=x+2x+1 f(x)=x|x|+2x (x 已知函数f(x)=x^3+x^2-2x-x,f(1)f(2) 已知f(x)+2f(1/x)=x+2/x+3,求f(x) 已知f (x)+2f(-x)=x^3+x^2,求f(x) 设f(x)={3x-1,x=0,求f(-x),f(x-2). f(x)+2f(-x)=3x+x的平方,则f(x)等于
