Answer:

$\boxed {(f-g)(x) = x^{2}+3}$

Step-by-step explanation:

<u>Given</u> :

f(x) = 2x² + 2
g(x) = x² - 1

Now, this problem can be used using a simple formula.

$\fbox {(f - g)(x) = f(x) - g(x)}$

Let's solve.

(f - g)(x) = 2x² + 2 - (x² - 1)
(f - g)(x) = 2x² - x² + 2 + 1
(f - g)(x) = x² + 3

∴ The answer will be x² + 3.
