Great initiative buddy.....
Q.1

1)
Even function
2)
Odd function
3)
Neither even nor odd function
4)
Data Insufficient

Its option 3..
The function f(x)-g(x)=x^2-x^3+17
f(x)!=f(-x)
f(x)!=-f(-x)
hence should be 3...
billu bhai great initiative...wil be as active as possible
Q.2
The value of the quadratic function f(x) = ax
2 + bx + c is minimum for x = -2.5. Also, it is known
that f(-2) = -2f(3).
1. Find the product of the roots of f(x).
1) 14 2) -14
3) -9 4) 9
5) Cannot be determined
2. Determine the minimum value of f(x).
1) -60.75 2) -91
3) -2.5 4) -121.5
5) Cannot be determined
PS: Please post Question NUmber/Set No while posting a question or answering it, will make life easier!!!
Q. 3
If f(a, 0) = 2a - 1
f(0, b) = b - 3
f(a, b) = f
Then,
f(99, 243) is equal to
1)33
2)37
3)36
4)35
Q3
4)35

Second wala sir??
Q.1
OA
3)
Neither even nor odd function
All of us got it right!! Nice start...
Q2.
1) -14
2) -2.5 
Q3.
i would say the answer is 35.
f(99,243) = f
= f
so, this can be reduced to f = 2*18-1 = 35

1) products of roots = -14 (equation is--> x2+5x-Product)
sum of roots = -(b/a) and it's given -(b/2a)=-2.5)

Q 2. 1) -14
2) cannot be determined (since b and c can be expressed in terms of a but minimum value will depend on the value of a which is not known.)
Set 2
OA
!) -14
2) Cannot be determined (since b and c can be expressed in terms of a but minimum value will depend on the value of a which is not known.) as said by bindita..
Teesra bhi kar lo puys...next set thodi der me post karta hu..
Set 5
If log10 (y 21) + log10y = 2, which of the following is the value of y?
10
25
4
10
1)
(i) or (iv)
2)
(iii) only
3)
(ii) or (iii)
4)
Cannot be determined
5)
None of these
Set 5
log10(y-21)y = 2
log(y-21)y/log10 = 2
log (y-21)y = log 100
y^2-21y-100 = 0
y = -4,25
but we cannot take -ve log so y =25
therefore only 2.
none of these..
