The Range of the function f(x) = (x - 2) / (2 - x) is
A) -1 to 1
B) 0 to 1
C) -1 to 0
D) None of above

• D) None of the above
  As here f(x)=-1 Hence Range will also be {-1} because Range of a constant function is constant itself while its domain is x2. Why you guys are putting x=2? At this point function is undefined and that's how we find domain.

• ans is D
  because when put x=2 then (2-2)/(2-2) =0/0 then values come upto infinity

• A) -1 to 1 when x = -1,0,1 the value of function f(x)= -1
• 9 years agoHelpfull: Yes(1) No(9)
• D) none of above
  because for all values of x in domain i.e R- {2} , f(x)=-1.

• well when i hit and trial using options a b and c then in every case the answer comes -1.but when put option (d) the ans comes infinity..so what should i conclude from here!!
• 9 years agoHelpfull: Yes(0) No(4)
• x-2>0 and 2-x2 and x
• 9 years agoHelpfull: Yes(0) No(2)
• C) take any value of x we will get -1 and if u take 2 u will get 0 so the ans is option c
• 9 years agoHelpfull: Yes(0) No(4)
• -1 to 0
  or 0
  pl xpln..clrly..
• 9 years agoHelpfull: Yes(0) No(0)
• range is -1 so ans is d

• in chess board remove 4 square block from four corners where given side of square is 30cm then area of square is
  A) 2000 B) 2000/9 c) 9000 D) i dont remeber 4 th option
  
  Sol:
  Ans = 2000....now can you explain how ans is 2000 ??? u've commented ans of this qn somewhere
