Answer:
{14,23,654,0,9}
Step-by-step explanation:
The first three contain negative numbers and decimal points therefor the last one {14,23,654,0,9} is correct.
Make it a trinomial by using the FOIL method.

What is Function?</h3>
A function is defined as a relation between a set of inputs having one output each.
According to the question,
![a(x) = 3x + 1 \\\\b (x) =\sqrt{x+4}](https://tex.z-dn.net/?f=a%28x%29%20%3D%203x%20%2B%201%20%5C%5C%5C%5Cb%20%28x%29%20%3D%5Csqrt%7Bx%2B4%7D)
To find the domain of the composite function,
![(b o x) (x) = b(a(x))\\\\(b o x) (x) = b(a(3x-1))\\\\(b o x) (x) = \sqrt{3x+ 1 -4} \\\\(b o x) (x) = \sqrt{3x -3}\\\\](https://tex.z-dn.net/?f=%28b%20o%20x%29%20%28x%29%20%3D%20b%28a%28x%29%29%5C%5C%5C%5C%28b%20o%20x%29%20%28x%29%20%3D%20b%28a%283x-1%29%29%5C%5C%5C%5C%28b%20o%20x%29%20%28x%29%20%3D%20%5Csqrt%7B3x%2B%201%20-4%7D%20%5C%5C%5C%5C%28b%20o%20x%29%20%28x%29%20%3D%20%5Csqrt%7B3x%20-3%7D%5C%5C%5C%5C)
Therefore,
![3x - 3 \geq 0\\3x \geq 3\\x \geq 1\\\\](https://tex.z-dn.net/?f=3x%20-%203%20%5Cgeq%200%5C%5C3x%20%5Cgeq%203%5C%5Cx%20%5Cgeq%201%5C%5C%5C%5C)
Hence , [ 1, ∞ ] is is the domain of (b o a)(x).
