The graphs of functions f1 (x) = {(1, if x 0), (x2 + 1, if 0 < x < 2), (5, if x ≥ 2), f2(x) = log1/2(x - 3), f3(x) = 23 – x and f4(x) = e{x} where {.} denote the fractional part function are given (not in order) as :
The correct order of graphs of functions f1 (x), f2 (x), f3 (x) and f4 (x) is
(A) ABCD
(B) ACBD
(C) CBDA
(D) ADCB
