f(x)在x=0处连续,当x→0时 f(x^2)/x^2=1,则f(0)=?

设f(x)在点x=0处连续,当x不等于0时f(x)=2^(-1/x^2),则f(0)=? 设f(x)在x=0处连续,当x趋向0时f(x)/x的极限等于1,则f(0)+ f’(0)的值 f(x)定义在(0,+无穷大) 当x>1时 f(x)>0,且f(xy)=f(x)+f(y) 解不等式f[x(x-1/2) 当k=()时,函数f(x)=x^2+1 = 0并且 f(x)=k x=0,在x=0处连续 f(x)是偶函数,x大于等于0时,f(x+2)=f(x) 当x[0,2)f(x)=log2^(x+1) 则f(-2010 设f(x)当X＞0时连续∫f(x)dx=2x/(1+x^2)+C,求f(x) f(x)连续且f(x)=x+(x^2)∫ (0,1)f(t)dt,求f(x) 若f(x)在x=0处连续,且当x趋近于0时,limf(x)/x 存在,证明f(x)在x=0处可导. f(x)在x=0处连续,且x→0时,lim (f(2x)-f(x))/x = A(常数).求证 f(x)在x=0处可导, 求lim（x→0）[(xf'(x))/(2f(x))]^(1/x),其中f(x)在x=0点某邻域内有三阶连续导数,f(0 对任意实数x,满足f(2x)=f(x),f(x)在x=0时连续,证明f(x)是常数 f(x)在[0,1]连续,f(x)=3x-√(1-x^2)[∫f^2(x)]dx,求f(x)
