If `f(x) = | x |/x` ; x! = 0 then f(x) - f(-x) is equal to

If f(x)=x+3, then f(x)+f(-x) is equal to

If f : R rarr R be defined as f(x) = 2x + |x| , then f(2x) + f(-x) - f(x) is equal to

Let f(x) = x|x| then f'(0) is equal to

If f(x)=log|2x|,x!=0 then f'(x) is equal to

If f(x)=x,x 0 then lim_(x rarr0)f(x) is equal to

If f:R rarr R be defined as f(x)=2x+|x| then f(2x)+f(-x)-f(x) is equal to

If f'(x) = f(x)+ int _(0)^(1)f (x) dx and given f (0) =1, then int f (x) dx is equal to :

If f(x)=|x|, then f'(x), where x ne0 is equal to

If f(x) is a continuous function satisfying f(x)f(1/x) =f(x)+f(1/x) and f(1) gt 0 then lim_(x to 1) f(x) is equal to

If f(x)=(1)/(1-x), then f(f(f(x))) is equal to
