f(x)=0.5(x 2)^2 10

f(X)=f(X+2)(xf(X)=f(X+2)(xf(X)=f(X+2)(x-3

f(x)=x/(1+x^2)^0.5求f(f(f(x)))f(x)=x/(1+x^2)^0.5求f(f(f(x)))f(x)=x/(1+x^2)^0.5求f(f(f(x)))f(f(f(x)))=x/

若函数f(x)=x-2x>10f(f(x+6))x若函数f(x)=x-2x>10f(f(x+6))x若函数f(x)=x-2x>10f(f(x+6))x根据条件,当x＜10时f(x)=f(f(x+6))

f(x)=x^2+x(xf(x)=x^2+x(xf(x)=x^2+x(x你的条件好像不全吧,请你把题完整的给出来.后面的f(-x)有没有另加条件,比如x>0这个条件?
