If f(x) = `x/(1 + |x|) ` for x ` in R ` then f(0) is equal to

if f(x) = x-[x], in R, then f^(')(1/2) is equal to

if f(x) = x-[x], in R, then f^(')(1/2) is equal to

Let f:R rarr R be defined by f(x)=2+alpha x,alpha!=0 , If f(x)=f^(-1)(x) , for all x in R , then alpha equals

Function f satisfies the relation f(x)+2f((1)/(1-x))=x AA x in R-{1,0} then f(2) is equal to

If f(x)=9x-x^(2) , x in R , then f(a+1)-f(a-1) 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 : R rarr R be defined as f(x) = 2x + |x| , then f(2x) + f(-x) - f(x) is equal to
