Let `f:R->R` be a continuous function such that `|f(x)-f(y)|>=|x-y|` for all `x,y in R` , then `f(x)` will be

Let f:R rarr R be a function such that |f(x)-f(y)|<=6|x-y|^(2) for all x,y in R. if f(3)=6 then f(6) equals:

Let f:R->R be a function such that f(x+y)=f(x)+f(y),AA x, y in R.

Let f:R->R be a function such that f(x+y)=f(x)+f(y),AA x, y in R.

Let f:R to R such that f(x+y)+f(x-y)=2f(x)f(y) for all x,y in R . Then,

Let f:R to R such that f(x+y)+f(x-y)=2f(x)f(y) for all x,y in R . Then,

Let R be the set of all real numbers. Let f: R rarr R be a function such that : |f(x) - f(y)|^2 le |x-y|^2, AA x, y in R . Then f(x) =
