Question

A.A^b means a raised to the power of



b.If f(x)=ax^4-bx^2+x+5 & f(-3)=2,then f(3)=?

Answer 1

Step-by-step explanation:

A. A^b means "A" raised to the power of "b"

B.

f(x) = ax^4 - bx^2 + x + 5

When f(-3) = 2

2 = a(-3)^4 - b(-3)^2 + (-3) + 5

2 = 81a - 9b + 2

2 - 2 = 81a - 9b

0 = 81a - 9b

81a = 9b

a/b = 9/81

a/b = 1/9

a = b/9

f(3) = ax^4 - bx^2 + x + 5

= a(3)^4 - b(3)^2 + 3 + 5

= 81a - 9b + 8

= 81(b/9) - 9b + 8

= 9b - 9b + 8

= 8
