a0 = a^3 and rest everything is zero
f(x) = a^3 x^2
so sirf AB nahi hua
From this A and B
But also D (f(x)=0 ke infinite solutions ho gaye)
Yeah I was getting A and B
Too
Key says acd tho
Notice the + in front of x^2 term in f(x). Question might be misprinted.
yeah that what i think too
wont C and D be ans too
D
multi correct
Yeah
So ABCD ?
B is wrong no? f(x)=0 if x=0 too
f(0) = 0
Not f(x) = 0
