Question

Let f : R → R is a function defined as f x = x - x : x i s o d d x - x + 1 : x i s e v e n , where [.] denotes the greatest integer function, then ∫ - 2 4 f x d x is equal to,

MARKS App · Accepted Answer

We know that, x – [ x ] = x ⇒ x – [ x + 1 ] = x – 1 Hence, ∫ - 2 4 f x d x = 6 . 1 2 1.1 = 3
