3) If F(X) = AF(X)4 + B(X)2 + X + 5 , F(– 3) = 2, then F(3) = ?
Read Solution (Total 8)
-
- f(-3)=af(-3)4+bf(-3)+(-3)+5
2=a*2*4+b*2+2
8a+4b=0
f(3)=af(3)4+bf(3)2+3+5
f(3)[1-4a-2b]=_8
multiply by 2 both sides
f(3)[2-(8a+4b)]=16
f(3)=8

- since value of even function is always
f(-n)=f(n)
so value of fn(3) will be 8A+4B+2 - 10 years agoHelpfull: Yes(1) No(1)
- answer is 8
81a+9b-3+5=2
=>81a+9b+5=5
now f(3)
81a+9b+3+5=5+3=8 - 10 years agoHelpfull: Yes(1) No(0)
- F(-3)=AF(-3)4+B(X)2+-3+5 = (5+(-3))= 2
5+X= 5+3 = 8 - 10 years agoHelpfull: Yes(1) No(0)

- question is wrong.
the correct is
If F(X) = AF(X)4 + BF(X)2 + X + 5 , F(– 3) = 2, then F(3) = ?

- SIMPLE SOLUTION
f(-3)=2
f(-2)=3
f(-1)=4
f(0)=5
f(1)=6
f(2)=7
f(3)=8
