Answer: The domain of the function 
is:
Interval Notation: (-∞ , -7) ∪ (-7 , 0) ∪ (0 , 7) ∪ (7, ∞)
Set-Builder Notation: { x | x ≠ 0 , 7 , -7 }
All real numbers besides 0, 7, and -7.
Step-by-step explanation:
In order to find the domain of your rational function, we need to simplify it:
Remember, most of the time, the domain of a rational function consists of all real numbers besides zero.
To find the domain, we equal the equations in the denominator to zero.
--> 
--> 
So all real numbers except for 0, -7, and 7 are in the domain of this rational function.
If Houa bought 11 chicken wings for $23.10.The cost of each wing will be $2.310.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, Houa bought 11 chicken wings for $23.10.
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group. Doing division is simple it is a type of operation in which we will distribute the items.
Suppose the cost of each wing is x.
x = $23.10 / 10
x = $2.310
Thus, if Houa bought 11 chicken wings for $23.10.The cost of each wing will be $2.310.
