Answer:
(f + g)(x) = 3x² + x + 5
(f - g)(x) = 3x² - x - 3
Step-by-step explanation:
(f + g)(x) → f(x) + g(x) → <u>3x² + 1</u> + <u>x + 4</u>
Combine like terms and you get: 3x² + x + 5
(f - g)(x) → f(x) - g(x) → <u>3x² + 1</u> - (<u>x + 4</u>)
Remember to distribute the neg. everything in the parentheses. Combine like terms and you get: 3x² - x - 3
