  List-I   List-II
(A) f-5+f0+f-1= (I) 16
(B) ff5+10 f-3= (II) 40
(C) ff-4= (III) -32
(D) fff1= (IV) -12
    (V) 19
The correct match is

  1. A ABCDIIIIIVI
  2. B ABCDVIVIIII
  3. C ABCDIVVIII
  4. D ABCDIVVIIII
Verified Solution

Answer & Solution

Correct Answer

(C) ABCDIVVIII

Step-by-step Solution

Detailed explanation

Given, fx=2x-5ifx<-3x+2if-3≤x<53x+1ifx≥5 Now solving all option one by one we get, A→f-5+f0+f-1=2×-5-5+0+5+-1+2=-12 B→ff5+10f-3=f3×5+1+10×-3+2 ⇒ff5+10f-3=f16-10=f6=3×6+1=19 C→ff-4=f2×-4-5=f13=3×13+1=40…
