Domain: (-∞,∞) OR All Real Numbers

Step-by-step explanation:

(f/g)(x) ⇒ f(x)/g(x) ⇒ x/1

Therefore, we look at the domain of the function x/1. There will almost always only be a gap if the denominator = 0. However, 1 ≠ 0, so therefore, there are no gaps or endpoints. Therefore, the domain is all real numbers

aliina [53]

Answer:

6.84

Step-by-step explanation:

1.60x4.5= 7.2

0.072x5=0.36 so subtract this by your total

7.20-0.36= 6.84
