amie  (9 years ago)

raviteja please explain this?how f(5)=25 when f(0)=96

Is this solution Helpfull? Yes (8) | No   

raviteja  (9 years ago)

f(1)=1^2=1,f(2)=2^2=4 so squares of given number f(5)=25

Is this solution Helpfull? Yes (3) | No (1)  

anil k   (9 years ago)

f(5)= 121, by theory of equations

Is this solution Helpfull? Yes (2) | No   

prachi tyagi  (9 years ago)

this function could be like
f(x)=96 if x=0
otherwise x2
so f(5)=25 is a correct solution

Tell me answer pls..........
wht about f(0)=96

Is this solution Helpfull? Yes (1) | No (1)  

hitesh taneja  (9 years ago)

let f(x)=ax^n+bx^n-1+........+constant
as 5 values are known let n=4 as many values can found
so from f(0) constant=96
From f(1) a+b+c+d=-96
form f(2) 16a+8b+4c+2d=-95
form f(3) 81a+27b+9c+3d=-92
form f(4) 256a+64b+16c+4d=-80
solving 4 equations simultaneously
we get a,b,c,d
and hence f(5)=

f(0)=96 is just meant to misguide people dear @priya

Is this solution Helpfull? Yes | No (1)  

somi  (9 years ago)

f(5)=5^5=25 as f(1)=1^1=1
f(2)=2^2=4
f(3)=3^3=9
f(4)=4^4=16

Is this solution Helpfull? Yes | No (2)  

Raghav gupta  (9 years ago)

25 start from 1 4 9 16 u will find difference is 3,5,7 and then 9 so 16+9=25.

Is this solution Helpfull? Yes | No   

Rahul kumar choudhary  (9 years ago)

putting the values on this equation you will able to find any values of given function,
49x^2-144x+96
therefore,
f(5)=601
