  1. A R(1,2)
  2. B R{1}
  3. C R{0,1}
  4. D R[1,2)
Verified Solution

Answer & Solution

Correct Answer

(D) R[1,2)

Step-by-step Solution

Detailed explanation

Given that, f(x)=1[x]-1 Domain =R-points at which f(x) is not defined Now, f(x) will be undefined, when x-1=0⇒x=1 Now, all the values for which the greatest integer function is 1. ⇒x∈[1, 2) Therefore, Domain of f(x) is…
