Let `f: R -> R`, be defined as `f(x) = e^(x^2) + cos x`, then `f` is a

For a real number x, let [x] denote the greatest integer less than or equal to x. Let f: R -> R be defined as f(x)= 2x + [x]+ sin x cos x then f is

Let, f: R rarr R be defined by f(x) = 2x + cos x, then f

Let f: R rarr R be defined as f(X) = 3x. Then

Let f: R to R be defined by f(x) = x^(4) , then
