6i knw what mistake u wid probably be makin in this quesn.....
HINT: check for the domain of the values in the bracket :)
Let f(x) be an increasing function defined on (0, ∞). If f(2a2 + a + 1) > f(3a2 – 4a + 1), then the number of integral values of a is/are
(A)5
(B)4
(C)3
(D)6

1I have written the right question. I am saying after checking the question again.
1(B)4 should be correct answer!
(only read futher if above answer is correct)
HINT:solve 2a2 + a + 1>3a2 – 4a + 1
1Kunl,the correct answer is (c).I have not read further as you said.
1thank you...always accept the truth and decline the false[1]
waise i would still say (B)[3]now read whats written in hidden further and tell if u can agree!..and might be the answer given in ur answer key is wrong!
1waise i don't know yaar i might be wrong too...but still i think my logic is correct so u see i would blame the answer only until someone else shows how (c) is correct!
but buddy why is it tht so many questions and answers from u turn out to be wrong?
1You are absolutely right kunl.The answer is really wrong.The answer is indeed 4.But tell me why do you apply that equation.Please illustrate it to me.
1I think it is the mistake of the book which is giving the answer as 5.
Thank you!
