Question

20+ [10-{81 +9- (24-5 of 4)}]​

Answer 1

Answer:

Consider the function f(x)=a(−720+1044x−580x2+155x3−20x4+x5)+x2+x

We have

f(2)=6,f(3)=12,f(4)=20,f(5)=30,f(6)=42

So the value at f(9) depends on the value of a where a is any real no.

for example if a=100 then

f(x)=

Then f(9)=252090.

So, I just wanted to point out that for such type of questions, the answer depends on your reasoning.
