The domain the function is 
.
In interval notation: [7, ∞).
The range of the function is in the interval (1, ∞).
The given function is 
.
The domain is x ≥ and the range is y ≥.
<h3>What is a function?</h3>
A technical definition of a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Now, 
⇒
Therefore, the domain the function is
The range of the function is the set of all values of y when we substitute the values of x.
Now, for 
So, the value of y in the interval (1, ∞).
Therefore, the range of the function is in the interval (1, ∞).

2(4z-3-21)=166-46
Combine like terms
2(4z-24)= 120
Distribute
8z-48= 120
Add 48 to both sides
8z= 168
Divide both sides by 8
z=21
Final answer: z=21
F+2/9=9 1/9
F=9 1/9-2/9
F=8 8/9
y- 14/9= 4 1/6
y=4 3/18+28/18
y=5 13/18
