Answer:
- Option D
Step-by-step explanation:
<u>Given:</u>
- f(x) = 1/ (x - 3)
- g(x) =
<u>The composite function f · g(x) is:</u>
- f(g(x)) = 1 / (
)
<u>Restrictions are:</u>
- x + 5 ≥ 0 ⇒ x ≥ - 5
and
≠ 3 ⇒ x + 5 ≠ 9 ⇒ x ≠ 4
<u>Combination of the above gives us the domain:</u>
- x ∈ [ - 5, 4) ∪ (4, +∞)
Correct choice is D
