HELP THIS IS URGENT I NEED IT SOON! PLEASE

If f(x) = x2 − 6x − 4 and g(x) = 5x + 3, what is (f + g)(−3)?
41
35
11
−35

Answer 1

11

Explanation:

(f + g)(x)

= f(x) + g(x)

= x² - 6x - 4 +5x + 3 ← collect like terms

= x² - x - 1

then

(f + g)(- 3) = (- 3)² - (- 3) - 1 = 9 + 3 - 1 = 11

Answer 2

11

Explanation:

F(–3)=(–3)²–6(–3)–4===> 9+18–4=23

g(–3)=5(–3)+3=‐15+3=–12

23–12=11
