f(x)=(x+5)^2-4 -6<=x
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
已知f(x)=6x^5+4x^4-3x^3+2x^2,g(x)=f(x)/(-1/2x)
已知:f'(x)=3X^4+2X^3+X+5,求f(x)
合并同类项x-f+5x-4f=x+5x-(f-4f)=6x+3f和x-f+5x-4f=x+5x+(-f-4f)=6x-5
已知f(3x+1)=9x^2-6x+5,则函数y(x)=[f(x)-4]/[f(x)+4x]的值域为_____.
x-2 ,X>=0 f(x)=f[f(x+5)],x分段函数f(x)= x-2 ,X>=0 f[f(x+5)],x
f(X)=f(X+2)(x
maple plot([f(x),f(x)+2,f(x)+4,f(x)+6],x = -10 ..10,y = -10
f(x)=x(x-1)(x-2)(x-3)(x-4) f'(1)=?
设f(x)=x^5+2x^4+3x^3+4x²+5x+6,证明f(x)=0至少有一实根
设函数f(x)=|x^2-4x-5|
已知函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)求f‘(2) 导数问题
