Question

f(x)=x^2-3x+9

g(x)=3x^3+2x^2-4x-9
Find (f-g)(x)

[] -3x^3-x^2+x+18
[] 3x^3+x^2-x-18
[] 3x^3+3x^2-7x
[] 3x^3-x^2-x

Answer 1

[AI-generated answer — Bot GPT 3.5]

(f-g)(x) = f(x) - g(x)

(f-g)(x) = (x^2 - 3x + 9) - (3x^3 + 2x^2 - 4x - 9)
(f-g)(x) = x^2 - 3x + 9 - 3x^3 - 2x^2 + 4x + 9
(f-g)(x) = -3x^3 - x^2 + x + 18

Therefore, the correct answer is: [] -3x^3-x^2+x+18
