A(x) = 3x + 1
b(x) = √(x-4)
Therefore

This composition of functions is only defined as a real number when x≥0.
Therefore its domain is x = [1,∞]
Answer: [1,∞]

<h2>
Put x =
I write the sum of 6x and 2x is at least 39 .</h2>
Step-by-step explanation:
We have,,
6x and 2x
To find, the value of x = ?
According to question,
The sum of 6x and 2x is at least 39
∴ 6x + 2x = 39
⇒ 8x = 39
⇒ x = 
∴ The value of x = 
Thus, put x =
I write the sum of 6x and 2x is at least 39 .
