  1. Answer:

    1) A^B means A raised to the power B. If f(x) = ax^4 – bx^2 + x + 5 and f(-3) = 2, then f(3) = ?

    a. 3

    b. 8

    c. -2

    d. 1

    Answer: b

    Explanation:

    f(-3) = a(-3)4- b(-3)2+ (-3) + 5 = 81a – 9b+ 2 = 2 So 81a – 9b = 0,

    f(3) = a(3)4- b(3)2+ (3) + 5 = 81a – 9b+ 8

    Substituting the value of 81a – 9b = 0 in the above we get f(3) = 8
