Question

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

Answer 1

`\large \boxed{\sf \ \ -3x^3-x^2+x+18 \ \ }`

Explanation:

Hello, please consider the following.

`(f-g)(x)=f(x)-g(x)=x^2-3x+9-(3x^3+2x^2-4x-9)\\\\=x^2-3x+9-3x^3-2x^2+4x+9\\\\=\boxed{-3x^3-x^2+x+18}`

Hope this helps.
