If the value of the algebraic formula AX3 + BX-1 is 9 when x = - 3, then the value of the algebraic formula AX3 + BX-1 is 9 when x = 3______ ．

If the value of the algebraic formula AX3 + BX-1 is 9 when x = - 3, then the value of the algebraic formula AX3 + BX-1 is 9 when x = 3______ ．

∵ when x = - 3, the value of the algebraic formula AX3 + BX-1 is 9, ∵ - 27a-3b-1 = 9, that is, 27a + 3B = - 10 ∵ when x = 3, AX3 + BX-1 = 27a + 3b-1 = - 10-1 = - 11

When x = - 2, the algebraic formula ax & # 179; + BX + 1 = 6. When x = 2, the algebraic formula ax ^ 5 + BX + 1 =?

Let f (x) = ax & # 179; + BX + 1, G (x) = ax ^ 5 + BX + 1
When x = - 2, f (- 2) = - 8a-2b + 1 = 6
That is - 8a-2b = 5
When x = 2, f (2) = 8A + 2B + 1 = - 5 + = - 4
Let f (x) = g (x) - f (x) = a (x ^ 5-x & # 179;)
Because f (x) is an odd function, then
F(-2)=-F(2)
So: G (- 2) - f (- 2) = - 24a
g(-2)=-24a+6=-18
=>
a=1
g(2)-f(2)=24
g(2)=24+f(2)=24-4=20
