Answer:
The domain of function 
is set of all real numbers.
Domain: (-∞,∞)
Step-by-step explanation:
Given:
the domain of both the above functions is all real number.
To find domain of :
Substituting functions 
and 
to find
The product can be written as difference of squares. ![[a^2-b^2=(a+b)(a-b)]](https://tex.z-dn.net/?f=%5Ba%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29%5D)
∴ 
The degree of the function is 2 as the exponent of leading term 
is 2. Thus its a quadratic equation.
For any quadratic equation the domain is set of all real numbers.
So Domain of is (-∞,∞)
Answer: Rita and Tina's total weekly wages can be represented as 11r + 32 + 11t or 11( r + t ) + 32
Step-by-step explanation:
Since, For Rita,
Charges per hour = $ 11
Working time = r hours,
Overtime charges for a week = $ 32,
Thus, her weekly charges = 11 r + 32
Now, For Tina,
Charges per hour = $ 11
Working time = t hours,
Thus, her weekly charges = 11 t
Hence, the combined weekly wages of both Rita and Tina = 11 r + 32 + 11 t
= 11( r + t ) + 32
Which is the required expression.
